Convert TSV to Excel
Tab-separated files come out of database exports, lab equipment, and log pipelines, and Excel opens them with a shrug at best. Converting to a real .xlsx gives you a workbook that behaves properly, with each TSV becoming its own sheet.
The parser detects the tab delimiter automatically (and lets you override it), builds a brand-new workbook locally, then reparses its own output to verify the row counts before you download.

How it works
Select one or more CSV/TSV files.
The delimiter and header row are detected; adjust if needed.
Each file becomes a worksheet in a brand-new workbook.
The output is reparsed to verify sheet and row counts, then downloads.
What the tool does
- Multiple CSVs into one workbook, one sheet per file
- Automatic delimiter detection (comma, semicolon, tab, pipe) with manual override
- UTF-8 BOM handling
- Fresh workbook output with no hidden structures, macros, or metadata
How the result is verified
The generated workbook is reparsed locally; sheet count and per-sheet row counts must match the parsed inputs.
Frequently asked questions
My export uses tabs but has a .txt extension. Will it work?
Yes, the tool reads .txt and .tsv alike and detects the delimiter from the content, not the file name.
Can I combine several TSV files into one workbook?
Yes. Select as many as you want and each becomes its own worksheet, named after the file.
