A browser-based tool for combining CSV files, with options for matching columns, cleaning rows, and formatting the output.

Landing page captured for the 2026-10-11 issue.

For: People combining exports with inconsistent columns
Worth noticing: Column matching can union headers or stack rows by position, with optional source-file tagging and duplicate removal.

Field notes

The interface separates appending rows from joining records, noting that this tool appends rather than performing a database-style join. It supports several delimiter and line-ending choices, and can add a UTF-8 BOM for Excel. A feedback prompt asks whether the merge worked, with an optional field for reporting what went wrong.
