Hi @Elad_Sharon,
A few questions:
- Have you tried uploading and extracting the data from an uploaded file using the upload component of Retool?
- Have you connected gsheet or sheets API to your retool resources?
What you're trying to do was something similar to the one I answered before but with an added initial process of converting an uploaded file to a data that can be passed on. If you can provide the details from the above question, we can guide you further.
