Google Docs, Sheets, and Slides size limits
Documents, spreadsheets, and presentations you create, as well as files that you upload, have some limits built in. For instance, files you create or upload that are larger than 25GB can’t be viewed within Google Drive. There are also limits, specific to file type, listed below.
Documents: 1,024,000 characters, regardless of the number of pages or font size. Uploaded document files that are converted to the Google documents format canâ€™t be larger than 2 MB.
Spreadsheets: 400,000 cells, with a maximum of 256 columns per sheet. Uploaded spreadsheet files that are converted to the Google spreadsheets format canâ€™t be larger than 20 MB, and need to be under 400,000 cells and 256 columns per sheet.
