Why this handles merging safely
Most "combine CSV" tools just stack files on top of each other. That's dangerous the moment your files have columns in a different order, or one file has an extra column, since data silently shifts into the wrong place.
- Columns are matched by their actual header name, not their position
- If a file is missing a column another file has, it's filled in blank, never guessed or misaligned
- Works with any number of files at once
Everything runs directly in your browser using JavaScript, your files are never uploaded, stored, or seen by anyone.
