Hi, Thanks for creating this issue! csv file import should just work out of the box, could you share the csv file here with us?

@vexersa if you look at the error carefully you can see that it seems it picked up the file mimetype as "excel's csv", I'm guessing there are some quote chars or linebreaks in your CSV.

Could you try either opening that CSV with Excel again or other software and saving as CSV again?

Excel's CSV and our usual "plain" CSV sometimes has differences in quote chars and linebreaks.

Hi guys,

@tjbck Unfortunately can't share because it has some sensitive data in it. 😔

@anzellai I have opened the CSV and resaved it using Excel. No luck.

Is there a size limit for the file?

@vexersa There's a soft limit for file sizes dictated by the RAM your environment has since the RAG parser loads the entire file into memory at once. How large is the file and how much ram does your docker host have?

Can you open the csv in notepad and see if there are is any excel meta data in the beginning of the file? If it's a plain CSV the file type should be "text/csv"

I was able to make a plaintext csv file that gets flagged as application/vnd.ms-excel, but I haven't had any problems with it getting parsed since the back end goes off of the file extension. The uploaded files are also stored on the docker host, so if they don't have enough disk space it could cause problems too.

I made a PR #554 that adds excel parsers, so you may be able to save it as an xlsx file and get it imported that way. The excel parsers are really slow though.

The Docker host has ~31GB available to it. The CSV is 24MB, but I've tested it with smaller .csvs of ~7MB. I don't think there is a disk space problem.

I've opened the file and don't see any excel meta data. 😕

I think there should be enough space, I haven't specified a limit in Docker Desktop but there's around 50GB free on the drive itself...

I can try the Excel parser PR, thanks!

Is there a list of file extension compatibilities?
Can we use something like vector DB's?

Thanks for the help!

The problem seems to have been some sort of encoding issue, I'll close this issue and merge the suggested PR above, Thanks!

Thanks but updating wasn't necessary, the solution was using a correctly formatted csv 🤝
