im trying to upload a csv file but it wouldnt

Hi @mention, nice to have you here 🙂
Can you please look into the notification center, and tell me if there is a red information showing the error?
Another workaround is to import the file via pandas into a dataframe and then calling .to_json("my_file.json"). Lastly, if the data doesn't contain confidential data, you can also share it with us and we'll look into it 🙂
