JSON to TSV Converter Online

What Is a JSON to TSV Converter?

A JSON to TSV converter transforms JavaScript Object Notation arrays into tab-separated values format. TSV is a tabular data format similar to CSV but uses tab characters instead of commas as field delimiters. This makes TSV particularly useful when your data values contain commas, as the tab delimiter avoids the need for field quoting. TSV is widely used in bioinformatics, scientific data processing, and as an import format for spreadsheet applications.

This converter takes a JSON array of objects and produces TSV output with the first row containing column headers derived from object keys and subsequent rows containing the values separated by tab characters. The conversion handles strings, numbers, booleans, and null values. The entire operation runs locally in your browser using client-side JavaScript, ensuring your data never travels to an external server.

How to Convert JSON to TSV

1. Paste your JSON array into the input panel. The tool expects an array of objects where each object represents a data row.
2. Click Convert to generate tab-separated output with headers from the object keys in the first array element.
3. Review the TSV output in the right panel. Columns are separated by tab characters, making the output compatible with spreadsheet paste operations.
4. Copy the TSV data and paste directly into Excel or Google Sheets where it will automatically split into columns, or download as a .tsv file.

Why Use PinusX JSON to TSV Converter?

Frequently Asked Questions

What is the difference between TSV and CSV?

TSV uses tab characters as field delimiters while CSV uses commas. TSV is advantageous when data values contain commas, as it eliminates the need for quoting. CSV is more widely supported but requires proper quoting for fields with commas, newlines, or quotes.

Can I paste TSV directly into Excel?

Yes. Copy the TSV output and paste it into Excel or Google Sheets. The spreadsheet application will automatically recognize tab characters and split the data into separate columns. This is one of the main advantages of TSV over CSV for quick data transfers.

How are nested JSON objects handled?

Nested objects are serialized as JSON strings in the TSV output since TSV is a flat tabular format. For best results, use JSON with a single level of key-value pairs. Complex nested structures should be flattened before converting to TSV.

Is there a row limit for conversion?

There is no imposed row limit. The conversion runs in your browser, so the practical limit depends on your device's memory. Typical devices handle thousands to tens of thousands of rows without any issues.

Does this tool process data on a server?

No. The entire JSON to TSV conversion runs locally in your browser using JavaScript. No data is sent to any server, no network requests are made during conversion, and no data is stored or cached anywhere outside your browser tab.

Your data never leaves your browser. 100% client-side processing.
