Convert JSON to TSV.

Drop a JSON file and get tab-separated values (TSV), one row per record. Nested objects and arrays are flattened into dot-notation columns — every value kept, structure not. Runs in your browser.

To convert JSON to TSV, drop or paste a JSON file — csvtodashboard parses it into rows and columns in your browser, then emits tab-separated values (TSV), one row per record. Fields are separated by tabs, so values full of commas stay in their own columns — handy for spreadsheet paste and database import. Nothing is uploaded; the whole conversion runs on your device.

01 · How it works

Three steps, then done.

This reads your JSON — an array of objects becomes rows, then writes tab-separated values (TSV), one row per record. Because TSV is a flat, tabular format, nested objects and arrays in your JSON are flattened into dot-notation columns (e.g. user.address.city) — that keeps every value but does not preserve the hierarchy, so the conversion is one-way. Everything runs locally in your browser.

i. drop

Drop or paste

Drag a file, click to choose, or paste data directly into the input pane.

ii. detect

We read the shape

Types are inferred so the output is correctly formatted — not strings everywhere.

iii. use it

Copy, download, or dashboard

Copy the output, download it, or hit 'Build dashboard' to chart what's in the data.

02 · Why ours

Smart TSV conversion by default.

Free TSV converters often produce sloppy output — every value quoted, types lost, errors swallowed. Ours infers types where it can, fails loudly when it can't, and pairs the conversion with a one-click path to a dashboard.

  • 01

    Correct types

    Numbers, booleans and nulls are preserved wherever TSV supports them — not every value dumped as a quoted string.

  • 02

    Local-first

    Your file is parsed and converted in your browser — verify in DevTools → Network. Nothing is uploaded, logged, or stored.

  • 03

    Fails loudly

    Malformed input gives a clear, specific error instead of silently wrong output — so you can trust what comes back.

  • 04

    One click to a dashboard

    Every conversion keeps a tabular copy, so you can send the data straight to our visualization tool to chart it.

Good to know

json to tsv notes.

Format-specific details worth knowing before you convert JSON to TSV.

  • Nesting is flattened, not kept

    JSON can nest objects and arrays; converting to TSV flattens them into dot-notation columns. Every value is preserved, but the hierarchy is not — it is a one-way conversion.

  • Tabs over commas

    Fields are tab-separated, so data full of commas stays in its columns — ideal for database bulk-import and paste-into-spreadsheet workflows.

  • Edge values are quoted

    The rare value containing a tab, quote or newline is quoted so the columns never drift out of alignment.

  • No formal spec

    TSV isn't formally standardized; Excel, pandas and most tools read this dialect, but quoting conventions vary between them.

03 · FAQ

json to tsv questions.

What JSON input works?
Any JSON that is an array of objects (the most common data shape); a single object becomes one row. Deeply nested JSON works too — it is flattened with dot notation.
Nested objects and arrays are flattened into columns using dot notation (user.name, user.address.city). Arrays of scalars are joined; arrays of objects are JSON-stringified into a single cell. Your data is preserved, but the nested structure is not — this is a one-way conversion.
Fields are separated by tabs; the rare value containing a tab, comma, quote, or newline is quoted so the file stays unambiguous and re-openable.
No. The whole json-to-tsv conversion happens locally in your browser — the file never touches a server.
