The TSV has no header row

Fix: Use a first row with field names so object keys can be generated correctly.

Fix: Use real tabs between fields for TSV input.

The rows have inconsistent column counts

Fix: Make sure each row matches the same number of columns as the header.

FAQ

What does TSV to JSON do?

It converts tab-separated rows into a JSON array of objects using the header row as keys.

Do I need a header row?

Yes. The header row is used to generate the JSON object keys.

Can it infer numbers and booleans?

This version keeps values as text strings for predictable output.

What is the difference between TSV to JSON and TSV to CSV?

TSV to JSON changes the structure into JSON objects, while TSV to CSV only changes the delimiter.
