What files can I upload to Merge CSV Files?

This tool currently accepts common formats up to 25MB per file, depending on the tool.

Runs are configured to expire automatically after a short period, at which point files and metadata are deleted by background cleanup jobs.

Tool

Merge multiple CSV files with the same columns into a single CSV.

Files are uploaded and processed in the background. You will see links to download your results when the run is finished.

Every run goes through the same Laravel queue pipeline so heavy files don’t block the interface.

Files live only as long as needed for processing and download, then cleanup jobs remove them.

Design, dev and ops teams can rely on a consistent interface instead of juggling one‑off tools.
