JSON to TSV Converter

JSON to TSV Converter turns a JSON array of objects into a tab-separated values file — a plain-text tabular format often preferred over CSV for data that may already contain commas, since tabs rarely appear inside real-world text. It automatically detects every unique key across your objects to build the columns, aligns rows even when some objects are missing certain keys, and safely escapes any field that happens to contain a tab, quote, or line break.

TSV is widely supported by spreadsheet tools, bioinformatics pipelines, and many command-line data utilities that expect a simple, comma-free tabular format.

• Automatic column detection: Every unique key across your JSON objects becomes a column, in the order first encountered.
• Handles sparse and nested data: Missing keys become empty cells; nested objects and arrays are safely stringified rather than dropped.
• Safe escaping: Tabs, quotes, and line breaks inside a value are quoted so the column structure never breaks.
• Instant, in-browser conversion: No upload, no server round trip, no account.
• Copy or download: Grab the TSV text directly or download it as a .tsv file.

1. Paste a JSON array of objects into the input box, or click "Load Sample" to see an example.
2. Click Convert to generate the TSV output.
3. Review the columns — every unique key across your objects becomes a header.
4. Copy the TSV or download it as a .tsv file.

Example 1: A JSON array of three user records with name, email, and role fields converts to a four-line TSV — one header row and three data rows — ready to import into a spreadsheet or data pipeline.

Example 2: A product export where descriptions naturally contain commas converts cleanly to TSV without needing to quote every field, since commas are not the delimiter.

• Comma-safe exports: Ideal for data containing commas without needing quotes everywhere.
• No column mismatches: Automatic key detection keeps every row aligned even with inconsistent objects.
• Widely compatible: TSV is supported by spreadsheet tools, data pipelines, and many command-line utilities.
• 100% private: Nothing is uploaded — conversion runs locally in your browser.
