It will then iterate through the values in the selected column and replace any instances of the Old Value with the New Value. > [!WARNING] > Important Considerations: > > - This step does not generate any output. Instead, it modifies the value within the same file that is being used within the Flow. > - The values given under the "Old Value" field must be the entire cell value. It will not replace any partial values within the defined cell. --- ## Properties #### Inputs    | Property | Description | Data Type | | --- | --- | --- | | File | The Excel or CSV file where the data is pulled from. | FileData | | File Type | The type of file being used by the step.
