WordPress itself does not support uploading CSV files. So the question is, which plugin are you using for this? You’ll need to contact that plugin’s support team with your issue.
If you’re getting a “Forbidden” error after editing the prices in the CSV, I would first check which import plugin you’re using. WordPress itself doesn’t handle CSV imports directly, so the error may be coming from the plugin, hosting security rules, or the CSV file format.
I’d also try exporting a fresh CSV from the original source, make one small price change, and test the import again. If that works, the issue is likely related to the edited file or its formatting.
Hope this helps you narrow it down.
