# Save Excel File

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Use the Save Excel File Action Step to save the changes to the Excel file being modified inside the
Excel Session at any point of the execution. For example, saving the Excel file after loop
operations serves as a way to prevent data loss in case the workflow execution stops because of an
unknown error. The Excel Session automatically saves the file at the end of its execution.

The Save Excel File Action Step works only inside an Excel Session. Specify the file to modify in
the [Excel Session](https://docs.mulesoft.com/rpa-builder/6.6/toolbox-excel-operations-excel-session).

> [!WARNING] Save Excel File cannot save the file if the Excel Session opens the file in read-only
> mode.

## Properties
