I have an "Import" (.csv file to an existing table) that has been working for years. This month, after installing latest Office update, the import no longer works, "Err: Invalid argument". I checked the file to be imported and it is formatted correctly.

    Dear LesDaNovice.

    Good day! Thank you for posting to Microsoft Community. I am happy to help you

    I noticed that you mentioned that the problem occurred after the Access version update.

    I noticed that you mentioned that the issue appeared after the Access version update, so it is possible that the application issue is caused by the version update, if so, it needs to wait for the developer to fix it.

    If it is convenient for you, could you please try to install the previous version of Office application, so that I can further confirm this problem, and I will also communicate this situation with the developer:

    Thanks for your cooperation.

    Have a good day！

    Tim,

    Thank you for replying to my request. I tried following the directions, but received and err when trying to do the update to a previous version of Office. This is the config.sys file I created:

    Err: "Something went wrong" Error Code: 30183-27 (400)

    I ran the setup.exe as an administrator.

    Thanks,

    Les___

    Please show the exact version and build of Access you have installed now.

    Is this import done via a VBA procedure? If so, please show us that procedure.

    Is this the only error? Does it occur on previously imported .csv files (you probably want to try this on a back up copy of the accdb so you don't accidentally overwrite data)?

    Access version: 2503 Build: 16.0.18623.20116 32-bit.

    Import is performed via a Saved Import

    The import has worked for several years; last time it worked was the end of February 2025. I only import into the db once a month. I tried re-creating the Saved Import in a copy of the database. It still doesn't work. This is the only err I receive. The rest of the db functions fine.

    Thanks for your help.

    Thank you.

    To be sure I'm following correctly.

    Were you able to reimport a previous csv that had been correctly imported last month?

    And, given that there may be more than one approach to importing files, can you be more specific about the import steps you follow?

    Specifically, in one of my accdbs, I run the import via a VBA procedure. In my testing. I used the ribbon options to attempt the import.
