There is a problem with the excel file from KOBO

Could you please advise me
What can be the error shown on the screenshot?

The data is downloaded from KOBO and then we open the downloaded Excel file and this window pops up.

And then the following window pops up.
I can’t understand what the problem is. There are no formulas in the form.

What does the log file say, please?

@Vlad_Dn, have you validated your XLSForm through this online validator to see if there are any syntax issues in your form? BTW, could you also let us know the server you are using?

Here is what the log says.
Almost the same as the screenshot above.

Yes, of course! I check all my forms through this tool. There are no errors.
Server here.
This questionnaire has been working for a very long time. This window appeared recently.
There are a lot of questionnaires coming in every day. Judging by the screenshot, Excel deleted some formula. Do you think it can be so that someone accidentally entered information and Excel perceives it as a formula and deletes it?

@Vlad_Dn, would you mind sharing with me the following information through a private message so that I could have a closer look at your case:

  • Username
  • Project name
  • Server

Note: You could share with me a private message as outlined in the post discussed previously:
