How to convert CSV to Excel
- 1
Add your CSV file
Drop in your CSV file — or any of CSV, TSV, Excel, JSON, or JSONL; the format is auto-detected. It is read in your browser, so nothing is uploaded.
- 2
Preview the result
Tabularly parses the file and shows it as a table, so you can confirm the columns and rows look right before exporting.
- 3
Download as Excel
Export as Excel — or any of CSV, TSV, Excel, JSON, or JSONL — and the file saves straight to your device.
Converting CSV to Excel
Converting CSV to Excel changes how the file is written while keeping the data identical — the same columns and the same rows, just in a different format. Tabularly reads your CSV, shows it as a table to confirm it parsed correctly, and exports clean Excel with no reformatting of your values.
You are not limited to one direction or one format: the converter auto-detects the input (CSV, TSV, Excel, JSON, or JSONL) and can export to any of them, so the same page handles round-trips and one-off conversions alike. Your headers and structure are preserved exactly.
The whole conversion happens in your browser, so your file never leaves your device — a real difference from converters that upload your data to a server. It is free with no signup and no watermark; Pro raises the file-size limit for large datasets.

Yes — every column and row is preserved as written; only the file format changes.
What input formats are accepted? +
CSV, TSV, Excel (.xlsx, .xls), JSON (array of objects), and JSONL (newline-delimited JSON). JSON vs JSONL is auto-detected, so you are not limited to CSV.
