Hello, I need to upload an Excel file, but this file doesn't have a header. The spreadsheet has several columns, and I'm having trouble getting the index of these columns in Retool because the parse on upload messes up the column index. Is there any way I can include a header before parsing?
I tried using an Excel library, but it seems that Retool doesn't recognize it. I also tried manipulating the keys through a transformer, but since there are many rows, the processing was becoming too heavy.
