Frequently Asked Questions

What is TSV and why convert to JSON?

TSV (Tab-Separated Values) is a simple file format where data fields are separated by tabs. Converting TSV to JSON allows you to use the data in web applications, APIs, and modern data processing workflows that prefer JSON's structured format.

Is my data safe?

Yes, absolutely! All conversions happen entirely in your browser. No files are uploaded to any server, ensuring complete privacy and security of your TSV data.

Can I convert multiple TSV files at once?

Yes, you can select and convert multiple TSV files simultaneously. The tool will process all files and combine the output into a single JSON document with separate arrays or objects for each file.

What output formats are supported?

The tool supports three output formats: Array of objects (each row becomes an object), Single object with arrays (each column becomes an array), and Nested object structure (hierarchical based on column relationships).

How are data types handled?

The converter can automatically detect and convert numeric values and boolean values (true/false) to their proper JSON types. You can disable this feature if you want all values to remain as strings.

Can I edit the JSON output before downloading?

Yes, the output textarea is editable. You can make any necessary adjustments to the JSON content before downloading the file, such as adding additional fields or modifying values.

What if my TSV has empty cells?
