Hi Nicholas,

Thank you for the clarification! The previously mentioned events indeed do not expose options for such customizations. The reason for that is there could be multiple formatting requirements and specific configurations depending on the use case, and it would be hard to cover all of them.

If you want to conditionally color only certain cells based on some condition, as you mentioned, you will need to access the actual cells of the Excel file. You may check this sample app for an example how custom export can be handled using the SpreadStreamProcessing library. It also demonstrates how to set different background color to some cells.

Having the above in mind, I have marked the request as "Declined" since we'd rather treat the scenario as custom approach. Please let us know if any further questions are raised after you revise the linked sample or if you'd need some assistance with the configuration.

Hi Nicholas,

We've exposed a couple of events that let you customize the files exported to Excel and CSV:

• OnBeforeExport - fires after the export was initiated (via button click or programmatically).
  
  
• OnAfterExport - fires after the OnBeforeExport event, and before the actual file is provided to the user.

You can subscribe to these events to modify the exported file as needed. Please take a look at the options their event arguments provide and let us know if there is any desired file manipulation that you cannot achieve through these events.

Thank you in advance! I'll be looking forward to hearing from you!
