PDFApp

Overview

This is a Google Apps Script library for managing PDFs.

Description

Google Apps Script is one of the most powerful tools for cloud computing. When Google Apps Script is used, the result can be obtained even when the user doesn't stay in front of the PC and mobile phone by the triggers. One day, there might be a case where it is required to manage PDF data using Google Apps Script. The combination of Google Docs (Document, Spreadsheet, and Slide) and PDFs is useful for various situations. However, unfortunately, there are no built-in methods for directly managing PDFs using Google Apps Script. Fortunately, it seems that pdf-lib of the Javascript library can be used with Google Apps Script. By this, PDF data can be managed with Google Apps Script using this library. This Google Apps Script library manages PDFs by using it as a wrapper between Google Apps Script and pdf-lib.

I have already published the following posts.

I created this library to more efficiently manage PDFs with a simple script by summarising the scripts of these posts.

setPDFBlob

Give the source PDF blob. This method is used with other methods.

In this sample script, the PDF metadata is retrieved.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

PDFApp.setPDFBlob(blob).getMetadata()
  .then(res => console.log(res))
  .catch(err => console.log(err));

useStandardFont

When you want to use the standard font, please use this method. This method is used with other methods.

In this sample script, a value is put into a field of PDF Form with "TimesRoman".

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const object = {
  values: [
    { "name": "textbox.sample1.sample1.page1", "value": "sample update text" }
  ],
};

PDFApp
.setPDFBlob(blob)
.useStandardFont("TimesRoman")
.setValuesToPDFForm(object)
  .then(newBlob => folder.createFile(newBlob))
  .catch(err => console.log(err));

useCustomFont

When you want to use the custom font, please use this method. This method is used with other methods.

In this sample script, a value is put into a field of PDF Form with a custom font.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const object = {
  values: [
    { "name": "textbox.sample1.sample1.page1", "value": "sample update text" }
  ],
};

PDFApp
.setPDFBlob(blob)
.useCustomFont(DriveApp.getFileById("###fileId of font file###).getBlob())
.setValuesToPDFForm(object)
  .then(newBlob => folder.createFile(newBlob))
  .catch(err => console.log(err));

exportPages

Export specific pages from a PDF blob.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const pageNumbers = [2, 4, 6, 8];

PDFApp.setPDFBlob(blob).exportPages(pageNumbers)
  .then(blob => DriveApp.createFile(blob))
  .catch(err => console.log(err));

In this sample, 2, 4, 6, 8, pages are exported. And, a new PDF file is created to the root folder.
This is from my post "Exporting Specific Pages From a PDF as a New PDF Using Google Apps Script".

getMetadata

Get PDF metadata from a PDF blob.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

PDFApp.setPDFBlob(blob).getMetadata()
  .then(res => console.log(res))
  .catch(err => console.log(err));

When this script is run, the metadata is retrieved from the inputted PDF blob.
When I tested this script, I noticed that the values of modificationDate and producer might be a bug in pdf-lib. modificationDate returns the execution time. producer always returns pdf-lib (https://github.com/Hopding/pdf-lib). I guessed that this might be a bug in pdf-lib. And, I would like to believe that this will be resolved in the future update.
This is from my post "Management of PDF Metadata using Google Apps Script".

udpateMetadata

Update PDF metadata of a PDF blob.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

const object = {
  title: ["sample title", { showInWindowTitleBar: true }], // This property is an array.
  subject: "sample subject",
  author: "sample author",
  creator: "sample creator",
  creationDate: new Date("2023-08-01T00:00:00"), // This value is date object.
  modificationDate: new Date("2023-08-01T10:00:00"), // This value is date object.
  keywords: ["sample keyword 1", "sample keyword 2", "sample keyword 3"], // This property is an array.
  producer: "sample producer",
};

PDFApp.setPDFBlob(blob).udpateMetadata(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, the metadata of "title", "subject", "author", "creator", "creationDate", "modificationDate", "keywords", and "producer" is updated. And, after the update is finished, a new PDF file is created in the root folder.
This is from my post "Management of PDF Metadata using Google Apps Script".
The detailed information of each property in the object can be seen at https://pdf-lib.js.org/docs/api/classes/pdfdocument.

reorderPages

Reorder pages of a PDF blob.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

const newOrderOfpages = [3, 1, 2, 5, 4]; // Please set new order of the pages in a PDF file. In this sample, the order of pages of the original PDF file is changed to 3, 1, 2, 5, 4.

const ignoreSkippedPages = true; // If this is false, when the PDF has 5 pages and "newOrderOfpages" is "[3, 2]", the exported PDF file has 5 pages of 3, 2, 1, 4, 5. If this is true, when the PDF has 5 pages and "newOrderOfpages" is "[3, 2]", the exported PDF file has only 2 pages of 3 and 2.

PDFApp.setPDFBlob(blob).reorderPages({ newOrderOfpages, ignoreSkippedPages })
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, a new PDF file is created with the new order of pages.
When the order of pages is changed, I thought that for example, when a PDF file has 5 pages and you want to replace only the 1st page and the 2nd page, the actual exported pages are 2, 1, 3, 4, 5. But, in this script, when ignoreSkippedPages is used as false, this can be achieved by newOrderOfpages of [2, 1]. On the other hand, when ignoreSkippedPages and newOrderOfpages are true and [2, 1], respectively, a new PDF file with only 2 pages of the 2nd page and the 1st page is created.
This is from my post "Changing Order of Pages in PDF file using Google Apps Script".

mergePDFs

Merge multiple PDF files in a single PDF.

const blob1 = DriveApp.getFileById("###fileId of PDF file 1###").getBlob();
const blob2 = DriveApp.getFileById("###fileId of PDF file 2###").getBlob();
const pdfBlobs = [blob1, blob2];

PDFApp.mergePDFs(pdfBlobs)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, the PDF of blob1 and blob2 are merged in order.
For example, if you want to merge 5 PDF files, please use const pdfBlobs = [blob1, blob2, blob3, blob4, blob5].
This is from my post "Merging Multiple PDF Files as a Single PDF File using Google Apps Script".

convertPDFToPng

Convert PDF pages to PNG images.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

PDFApp.setPDFBlob(blob).convertPDFToPng()
  .then(imageBlobs => imageBlobs.forEach(b => DriveApp.createFile(b)))
  .catch(err => console.log(err));

When this script is run, all pages of the PDF of blob are converted to PNG images, and those images are saved as the image files in the root folder.
This is from my post "Converting All Pages in PDF File to PNG Images using Google Apps Script".
When the number of pages is large, it might be better when the PDF is split by "exportPages" method.

getValuesFromPDFForm

Get values from PDF Form.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

PDFApp.setPDFBlob(blob).getValuesFromPDFForm()
  .then(res => console.log(res))
  .catch(err => console.log(err));

When this script is run, the values are retrieved from all fields of PDF form in the inputted PDF blob.
This is from my post "Retrieving and Putting Values for PDF Forms using Google Apps Script".

Limitations

In the current stage, the fields of the textbox, the checkbox, the dropdown list, and the radio button of the PDF Form can be used.

setValuesToPDFForm

Set values to PDF Form.

Limitations

In the current stage, the fields of the textbox, the checkbox, the dropdown list, and the radio button of the PDF Form can be used.

Sample 1

In this sample, the default font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

const object = {
  values: [
    { "name": "textbox.sample1.sample1.page1", "value": "sample update text" },
    { "name": "dropdownlist.sample2.sample1.page1", "value": "sample option5" },
    { "name": "checkbox.sample3.checkbox1.page1", "value": true },
    { "name": "checkbox.sample3.checkbox2.page1", "value": false },
    { "name": "checkbox.sample3.checkbox3.page1", "value": true },
    { "name": "radiobutton.sample4.page1", "value": "radiobutton.sample4.radiobutton2.page1" }
  ],
};

const PDFA = PDFApp.setPDFBlob(blob);
PDFA.setValuesToPDFForm(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, the values of object are put into each field of PDF form and a new PDF blob is returned.
About the names of each field of PDF form, they can be retrieved by "getValuesFromPDFForm" method.
This is from my post "Retrieving and Putting Values for PDF Forms using Google Apps Script".
The detailed information about the format of name and each properties can be seen in this post.

Sample 2

In this sample, the standard font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

const object = {
  values: [
    { "name": "textbox.sample1.sample1.page1", "value": "sample update text" },
    { "name": "dropdownlist.sample2.sample1.page1", "value": "sample option5" },
    { "name": "checkbox.sample3.checkbox1.page1", "value": true },
    { "name": "checkbox.sample3.checkbox2.page1", "value": false },
    { "name": "checkbox.sample3.checkbox3.page1", "value": true },
    { "name": "radiobutton.sample4.page1", "value": "radiobutton.sample4.radiobutton2.page1" }
  ],
};

const PDFA = PDFApp.setPDFBlob(blob).useStandardFont("TimesRoman");
PDFA.setValuesToPDFForm(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, the values of object are put into each field of PDF form and a new PDF blob is returned. At that time, "TimesRoman" is used from the standard font.
The font names of the standard font can be obtained from https://pdf-lib.js.org/docs/api/enums/standardfonts.
The detailed information about the format of name and each properties can be seen in this post.

Sample 3

In this sample, the custom font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();

const object = {
  values: [
    { "name": "textbox.sample1.sample1.page1", "value": "サンプルテキスト1" },
    { "name": "dropdownlist.sample2.sample1.page1", "value": "sample option5" },
    { "name": "checkbox.sample3.checkbox1.page1", "value": true },
    { "name": "checkbox.sample3.checkbox2.page1", "value": false },
    { "name": "checkbox.sample3.checkbox3.page1", "value": true },
    { "name": "radiobutton.sample4.page1", "value": "radiobutton.sample4.radiobutton2.page1" }
  ],
};

const PDFA = PDFApp.setPDFBlob(blob).useCustomFont(DriveApp.getFileById("###fileId of font file###").getBlob());
PDFA.setValuesToPDFForm(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, the values of object are put into each field of PDF form and a new PDF blob is returned. At that time, the custom font is used. For example, when you want to put Japanese language, the custom font is required to be used.
About the custom font, TTF and OTF files can be used.
The detailed information about the format of name and each properties can be seen in this post.

createPDFFormBySlideTemplate

Create PDF Form By Google Slide template.

About methods property in the object, the method name can be confirmed at the official document. Ref

Textbox: https://pdf-lib.js.org/docs/api/classes/pdftextfield
Checkbox: https://pdf-lib.js.org/docs/api/classes/pdfcheckbox
Dropdown list: https://pdf-lib.js.org/docs/api/classes/pdfdropdown
Radio button: https://pdf-lib.js.org/docs/api/classes/pdfradiogroup

For example, when you want to create a textbox, when { shapeTitle: "textbox.sample1.sample1", methods: [{ method: "setText", value: "sample text1" }]} is used, a textbox including sample text1 is created to the shape with the shape title of textbox.sample1.sample1.

Limitations

In the current stage, the fields of the textbox, the checkbox, the dropdown list, and the radio button of the PDF Form can be created.

Preparation

In this case, first, please create a Google Slide as a template as follows.

In the template slide, please set shapes and please set the shape titles. The shape title is required to be the unique value in the slide. Please be careful about this. The following script converts the template shapes to the fields of the PDF form using the shape titles. The flow of this is as follows.

Create a new Google Slide.
Put texts and shapes on the slide.
Texts are used as the text in PDF.

Shapes are converted to the fields in PDF form.
Set the ID to the shape title (Alt Text).

There is a rule regarding the format of ID. Please check the section “Rule of shape title (Alt Text)”.

Rule of shape title (Alt Text)

The format of ID (shape title (Alt Text)) is as follows.

{field type}.{group name}.{field name}

When the above sample Google Slide template is used, the IDs of fields of PDF form are as follows.

Textbox
- textbox.sample1.sample1
- textbox.sample1.sample2
Checkbox
- checkbox.sample2.checkbox1
- checkbox.sample2.checkbox2
- checkbox.sample2.checkbox3
Dropdown
- dropdownlist.sample4.sample1
Radiobutton
- radiobutton.sample5.radiobutton1
- radiobutton.sample5.radiobutton2
- radiobutton.sample5.radiobutton3

In the case of radiobutton.sample5.radiobutton1, radiobutton is a type of field. sample5 is a group of fields. radiobutton1 is a unique name of the group. radiobutton.sample5 has 3 fields of radiobutton.sample5.radiobutton1, radiobutton.sample5.radiobutton2, and radiobutton.sample5.radiobutton3.

embedObjects

Embed objects into PDF blob.

Limitations

In the current stage, the objects of texts and images can be embedded in a PDF.

Sample 1

In this sample, the default font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const object = {
  page1: [
    { text: "sample text1", x: 150, y: 635, size: 30 },
    { text: "sample text2", x: 390, y: 602, size: 16 },
    { imageFileId: "### file ID of image file ###", x: 175, y: 340, scale: 0.35 },
  ],
};
PDFApp.setPDFBlob(blob).embedObjects(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, 2 texts and 1 image are embedded to the 1st page of the PDF file with the default font.

- To
In this case, object is constructed as follows. By this, you can set the objects for each page.

const object = {
  page1: [
    { text: "sample text1", x: 150, y: 635, size: 30 },
    { text: "sample text2", x: 390, y: 602, size: 16 },
    { imageFileId: "### file ID of image file ###", x: 175, y: 340, scale: 0.35 },
  ],
  page2: [,,,],
  page3: [,,,],
  ,
  ,
  ,
};

Sample 2

In this sample, the standard font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const object = {
  page1: [
    { text: "sample text1", x: 150, y: 635, standardFont: "Helvetica", size: 30 },
    { text: "sample text2", x: 390, y: 602, standardFont: "TimesRoman", size: 16 },
    { imageFileId: "### file ID of image file ###", x: 175, y: 340, scale: 0.35 },
  ],
};
PDFApp.setPDFBlob(blob).embedObjects(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, 2 texts and 1 image are embedded to the 1st page of the PDF file with the standard font.

Sample 3

In this sample, the custom font is used.

const blob = DriveApp.getFileById("###fileId of PDF file###").getBlob();
const object = {
  page1: [
    { text: "sample text1", x: 150, y: 635, customFont: DriveApp.getFileById("### file ID of custom font file ###").getBlob(), size: 30 },
    { text: "sample text2", x: 390, y: 602, standardFont: "TimesRoman", size: 16 },
    { imageFileId: "### file ID of image file ###", x: 175, y: 340, scale: 0.35 },
  ],
};
PDFApp.setPDFBlob(blob).embedObjects(object)
  .then(newBlob => DriveApp.createFile(newBlob))
  .catch(err => console.log(err));

When this script is run, 2 texts and 1 image are embedded to the 1st page of the PDF file with the custom font. For example, when you want to use the Japanese language, it is required to use the custom font.
