I found the problem.
In excel A column is hidden. When selecting the related lookup column in Excel App, it shows the wrong column char (eg. E). Actually, Its column char should be D.
If there are no technical names in the testing phase and you do not pay attention to them, it is not possible to understand the error. Bacause of that there is a bug actually:
Bug Definition:
In case there is a hidden column in Excel when you select the lookup column, the Excel App selects the wrong column in the background. You can check it in the Test Section of the Excel App by checking the technical name of the lookup column.

Hey there, @Celil! Thanks so much for raising this in community and sharing what you found!
I did some digging around and it looks like there’s a similar issue with Google Sheets throwing errors when column A is hidden. It’s mentioned in the documentation here with an associated bug report on our end as well. I didn’t find any mention about this in the Excel documentation but it would make sense it would have similar issues.
I’d actually recommend opening a ticket with my teammates in support so they can dig into this a bit further and if need be open a bug report for Excel too. Please feel free to link them to the zap and this community thread for reference as well.
Thank you again for reporting this!
