CSV import is available on Explorer plans. Common CSV upload issues can be resolved by ensuring: • File has maximum 72 columns and 50,000 rows • Remove "created at" or "updated at" columns • Use UTF-8 encoded CSV with comma separators • Keep filename short • Remove commas, colons, and semicolons from data if fields get mixed up Try uploading to Google Sheets first, then download as CSV and re-upload if issues persist.

Hi, I tested CSV import on my end and it’s working correctly. Can you try uploading your CSV to Google Sheets first, then re-exporting it as a CSV and importing again? Let me know if you still run into issues.

Hi, Sorry about this. Can you share the CSV in a Google Sheet instead? That will help us check what might be causing the issue. Everything seems to be working fine on my end. Let me know if you have more questions.
