TSV to JSON Converter

Parse tab-separated values (TSV) and convert to JSON array format

Format Guide

TSV (Tab-Separated Values) uses tab characters to separate fields and newlines to separate records.

With headers: First line is treated as column names, each row becomes an object with named properties.

Without headers: Column names are auto-generated as column1, column2, etc.

Example:

TSV Input:

name	age	city John	30	NYC Jane	25	LA

JSON Output:

[
  {
    "name": "John",
    "age": "30",
    "city": "NYC"
  },
  {
    "name": "Jane",
    "age": "25",
    "city": "LA"
  }
]
Tips
  • • Use tabs (\t) as separators, not spaces
  • • Make sure each row has the same number of tabs/columns
  • • Empty cells will be converted to empty strings
  • • All values are converted to strings in the JSON output
More about the TSV to JSON

A comma shows up constantly inside real data, an address, a product description, a number written with a thousands separator, which is exactly why CSV needs quoting rules to avoid breaking on a value that contains one, while a tab almost never appears inside an actual data value, making tab-separated data a naturally safer export format for content that would otherwise need careful escaping. This tool converts tab-separated data into JSON with automatic header row detection and type inference, correctly turning a column of numeric-looking values into actual JSON numbers rather than treating every value as a raw string. Useful for converting a TSV export into JSON without CSV's comma-escaping headaches, getting numeric and boolean columns correctly typed instead of left as strings, or converting tab-separated data copied from a spreadsheet into structured JSON automatically.
