CSV Merger
Merge multiple CSVs into one.
Stack CSVs together
Paste several CSVs and this combines their rows into one file, aligning on the shared header so columns stay in order. It is the quick way to consolidate monthly exports into a single sheet.
It is the routine consolidation task — stitching twelve monthly exports into one annual sheet, or combining regional files — done in seconds without a spreadsheet formula.
Match your headers
Files should share the same columns for a clean merge. Everything runs in your browser, so the combined data never leaves your device. Your files are combined on your device and never uploaded.
