Maximum CSV File Size for Clay Uploads and Solutions to Split It

·Aug 22, 2025 12:32 PM·

Hi! I am uploading a CSV onto the Clay workbook but the issue is that the file size is 1.47GB and Clay is telling me its too large. What is the max file size I can upload? Do you have any other ideas how I can break up this file to upload it?

Hey Ammar K. — clay CSV upload cap is 250MB per file, so 1.47GB will be too big the easiest fix is to split your CSV into smaller chunks (there are free tools like split-csv or even Excel/Google Sheets if it opens). Another option is to load it into Google Sheets or BigQuery and then connect that source to Clay instead of uploading directly.
