How to use this tool
Choose two to four CSV files with identical column headers, and download the combined result.
Before you begin
Files must have matching headers. Up to four files, 4 MB each, and 15,000 combined rows.
Why keep files local?
The tool reads the input with your browser and processes it on your device. It does not send your file to a Workpico conversion API. If you share a result by copying or downloading it, you control what happens next.
