If you are seeing the "No Data" error after uploading a teacher or student spreadsheet you may have uploaded the blank template by mistake. This means that the file you uploaded contains the correct column headers but no student or teacher data in the rows below.
There could be two reasons the spreadsheet is blank:
- You added student or teacher rostering data to a different, saved spreadsheet.
- You added student or teacher rostering data to an earlier version of the same spreadsheet.

Restore an earlier version of the same spreadsheet
If you remember adding data to your spreadsheet and saving it, you might have removed the data by mistake and tried to upload an empty spreadsheet. Follow the directions below to restore an earlier version of the same spreadsheet.
Excel (Windows)
| Version history in Office only works for files stored in OneDrive or SharePoint in Microsoft 365. |
- Open Excel and then click File in the top left corner of the toolbar. The File tab opens.
- Scroll down the left navigation pane and select Info. The Info tab opens.
- Click the Version History button.
- Note: If you have not enabled Version History, a window opens asking you if you want to turn it on. This means there is not an earlier saved version of the file you can revert to.
- Select the version you wish to view. It opens in a new window.
- When you find the previous version and would like to restore it, click Restore.
Numbers (Mac)
- In the Numbers spreadsheet you just opened, click File in the top left corner of the toolbar. The File menu opens.
- Select Revert To from the file menu, and then choose Browse All Versions. The window updates to show an image of the current version of your spreadsheet on the left and a stack of images of previous versions on the right.
- To view earlier versions, click tick marks along the timeline or click the arrows next to the stack of spreadsheet images on the right, then click an image to view the version full size.
- After you have chosen the version you wish to restore you can do one of the following
- Restore this version: Click Restore below the spreadsheet image. A restored version of the spreadsheet replaces the current version on the right.
- Save a copy of the version displayed on the right as a new spreadsheet: Hold down the Option key on the keyboard, then click Restore a Copy. Numbers opens the spreadsheet copy in a new window, where you can edit it and save it with a new name. Example name: "Marshall Academy_Students2021"
| If you didn't find a version of the spreadsheet that you want to restore, click Done to exit. |
