This article explains how to insert an Excel sheet into your 4S Board.

Microsoft does not allow Excel files to be edited through third-party websites.
Any changes to the sheet must be made directly in Excel / OneDrive.
Open OneDrive.
For Door Line users, the file is stored in a shared folder from the bot account.
Navigate to:
Side Panel → Shared → Folder → 4S
Open the folder and select your Excel sheet.

Open the Excel file.
Go to File → Share → Embed this workbook.

When the embed box appears, set the dimensions to 800 × 650.

Copy the embed code.
Paste the copied embed code into the appropriate Excel Insert field on your 4S Board.
Go to your card > General text & look for the Source code button.

Click on that & paste your embedded code.

Note: If text is already present, paste it underneath.
