# Can I Add a Column in a Google Sheet that is Not Overwritten by Datachamp?


## ${color}[#1a63ba](Google Drive / Google Sheets)

Yes, you can add a column in your Google Sheet that won’t be overwritten by DataChamp while still allowing daily updates. For example if you want a supplier to manually fill in a column.

1. Set the Storage to Google Drive / Google Sheets.
2. Set the File Type to "Google Sheets" and select "[Append](https://help.datachamp.io/en/article/append-rows-in-google-sheets-with-custom-columns-16wb9xu/)".![](https://storage.crisp.chat/users/helpdesk/website/-/d/0/0/f/d00f55635133d800/scr-20260203-jiru_1f4cmga.png)
3. Set the [Export Mode](/en/article/export-mode-35l3c/) to "Incremental"![](https://storage.crisp.chat/users/helpdesk/website/-/d/0/0/f/d00f55635133d800/incremental_1ljvfw7.png)
