Use cell history to view the changes made to data in a grid. You can view changes made to data for the whole grid or for specific cells in a grid, over a selected period of time.
Cell history enables you to see how and when data in a grid was changed, and by whom. You can also view all the changes made to the values in a range of cells in a grid, and retrieve previous cell values. To do this, view the change history of a single data cell, row or column, a range of cells, rows or columns, or the entire grid.
All users can view data changes for a single cell or selected cells; modeling changes are not shown, only changes to data values. Users can only see the history of data they have access to.
To view a history of cell changes:
- Select the cells for which you want to view the change history.
Tip: You can select a single cell, a range of adjacent cells, or one or more columns or rows. To select all visible cells in a module, click the top-left cell. - Click the Cell history icon in the top right of the grid, above the column headers.

The following time periods display:
- Last 24 hours
- Last 7 days
- Last 30 days
- All
If you select All, the history of all data changes ever made to your selected cells displays. There is a caveat to this. Step 4 talks about the maximum number of items the Cell history dialog displays. - Date range
- Select a time period.
If you select Date range, a dialog displays. To confirm a date range, enter dates into the From and To fields (or select a date from the date picker). - Click Confirm.
The Cell history dialog displays the data values. This includes the date and time of the change, and the user who made the change.
Important: The retrieval of All changes can take some time, especially in large models. - Review the change history in the Cell history dialog.
A maximum of 1,000 changes are displayed. - Click Close.
The Cell history dialog closes and the grid displays.
