Frequently Asked Questions

Is my data safe?
Yes. Every conversion runs entirely inside your browser. No data is ever transmitted to a server. The tool works offline once loaded.
What is the maximum file size?
There is no hard limit. Files under 1 MB convert instantly. Files 1–10 MB show a progress indicator. Files over 10 MB prompt a warning and run in a background thread to keep the browser responsive.
Why does my TSV fail to parse?
Common causes are trailing commas, single-quoted strings, unquoted keys, or missing closing brackets. The converter auto-repairs many of these and tells you exactly what it changed.
Can I convert multiple files at once?
The tool handles one file at a time. For bulk conversion, consider the csvjson CLI or API.

How it works

Step 1

Tab delimiter auto-detected, then converted to .xlsx

Same as CSV to Excel — the tab delimiter is detected and the data is written to an Excel workbook with correct cell types.

Example

Git log export to Excel

Input
hash	author	date	message
abc123	Alice	2024-01-15	Fix memory leak
def456	Bob	2024-01-16	Add rate limiting
Output
Excel .xlsx with hash, author, date (as date values), and message columns

Frequently asked questions

Are leading zeros preserved in TSV to Excel?

Yes — the same leading-zero detection that applies to CSV to Excel applies here.
