How many rows can be processed at one time?
File upload limit: 25,000 rows per file
When uploading files directly to Dropcontact, you can process up to 25,000 rows per file.
If your file exceeds this limit, you'll see this message:
â ïž Be careful! Too many lines in your file. Please submit files with less than 25,000 lines.

Quick fix: Split your file into smaller files (under 25,000 rows each) and upload them one by one.
