Differences between Recognized v in cellData and p.body.dataStream

[IchiharaGaku]

I implemented a function to fetch added data upon button click using Univer Sheet on Next.js:

const snapshot = activeWorkbook!.getSnapshot();
const sheetData = Object.values(snapshot.sheets).find((sheet) => {
  return sheet.id === sheetName;
});

When examining added data in a sheet, some data is retrieved as value while others are in p.body.dataStream, causing undefined issues when accessing value.

Question
In what cases is data recognized as dataStream instead of value ?

When cell content contains rich text, it uses the p property to store the data. You can find more details here: https://univer.ai/guides/sheet/getting-started/cell-data#rich-text.
