TSV to JSON Converter

This tool converts tab-separated values (TSV) into structured JSON instantly. It’s ideal for turning spreadsheets, TSV logs, or flat tables into readable, key-value JSON format. You can paste or upload your TSV data, tweak a couple of settings, and get clean, formatted JSON on the fly.

Paste your input above or import a file below.

How to Use:

Paste your TSV content into the left input box. You can also upload a .tsv or .txt file using the Choose File button. Then adjust the conversion behavior using the Options:

  • First row is header: Uses the first row of your TSV as keys for JSON objects. If disabled, the tool returns a JSON array of arrays instead.
  • Trim values: Removes extra whitespace from each field before converting.

As soon as you enter or import data, the JSON output appears instantly on the right. Click Copy Output to copy the result, or use Export to File to download it. Press Clear All to reset the tool.

What the TSV to JSON Converter Tool does:

It parses TSV line by line and splits each row by tab. When headers are enabled, the tool uses the first row as column keys and converts each subsequent row into a JSON object. Without headers, the output is a nested array. All characters are escaped and validated for clean, standard JSON output.

Example:

Input TSV:

name	age	city
Alice	28	Paris
Bob	34	Berlin

Output JSON:

[
  {
    "name": "Alice",
    "age": "28",
    "city": "Paris"
  },
  {
    "name": "Bob",
    "age": "34",
    "city": "Berlin"
  }
]

Common Use Cases:

Use this tool to convert spreadsheet data into structured JSON for APIs, front-end apps, or config files. It’s especially helpful for importing/exporting table-based data between systems or when preparing flat files for integration into more structured workflows. No coding required just paste, preview, and export.
