Frequently Asked Questions

What is TSV and how is it different from CSV?
TSV (Tab-Separated Values) uses tab characters to separate fields, while CSV uses commas. TSV is common in database exports, Google Sheets copy-paste, and scientific data. The advantage of TSV is that tabs rarely appear in data, so quoting is less necessary than with CSV.
Does the tool auto-detect tab delimiters?
Yes. The Auto-detect mode examines the first line of your input and identifies whether tabs, commas, or semicolons are used as delimiters. If your data uses tabs, it will be detected automatically. You can also manually select Tab as the delimiter for certainty.
Can I paste data directly from Google Sheets?
Yes. When you copy cells from Google Sheets and paste into the tool, the data arrives as tab-separated text. The tool auto-detects the tab delimiter and converts it to JSON. This is a direct way to move spreadsheet data into JSON format.
How do I convert a TSV file from a database export?
Upload the .tsv file using the Upload button, or open it in a text editor, copy the contents, and paste into the input area. The tool handles both approaches. Make sure the first row contains column headers if you want JSON with named keys.
Does it preserve data types or is everything a string?
The JSON output treats all values as strings, which is the safest approach for CSV/TSV data where type information is not encoded. If you need typed values (numbers, booleans), parse the JSON output in your application and convert fields as needed.
