Extract Markdown tables and get JSON arrays of objects with auto type coercion.
Free Markdown Table to JSON Converter finds GFM pipe tables in a Markdown document and emits them as a JSON array of objects, keyed by the header row. Numeric strings coerce to numbers, 'true'/'false' coerce to booleans, and 'null' becomes JSON null — all optional toggles. Supports extracting the first table or every table in the doc.
Privacy: This tool runs entirely in your browser. Your text is never uploaded, logged, or cached. Close the tab and it's gone. Verify in DevTools → Network: zero requests fire.
Turning a Markdown spec into a JSON test fixture, or a README comparison table into a config, is a constant chore for developers. The converter runs 100% in your browser, and no data ever leaves your machine.

Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.
The converter recognizes standard GitHub-Flavored Markdown pipe tables — a header row, a separator row of dashes with optional alignment markers (:---, :---:, ---:), and one or more data rows. Alignment hints are parsed but don't affect the JSON output; the column order follows the header row.
For the opposite direction, use the Free JSON to Markdown Table Converter.
By default, numeric strings like 42, 3.14, or -7 are coerced to JSON numbers, and true/false (any case) are coerced to booleans. This makes the output directly useful as a config object or a test fixture. Toggle either off to keep all values as strings — useful when your table has columns that look numeric but aren't (product codes, zip codes, phone numbers).
For editing the source table visually, use the Free Markdown Table Generator.
By default, only the first table is extracted. Switch to All tables to walk the entire document and emit one combined array with rows from every table. Rows from later tables use their own header row as keys, so the output may have heterogeneous object shapes — useful for aggregating related tables into a single JSON blob.
The Pretty print toggle switches between human-readable output (2-space indent, one field per line) and a compact single-line format suitable for embedding in another JSON file or a shell pipeline. Stats at the top of the output show table count, row count, and column count so you can sanity-check the result at a glance.
Once you have JSON, render it back to Markdown with the Free JSON to Markdown Table tool to verify a round-trip.
Drop in a document that contains at least one GFM-style pipe table.
First table only or all tables. Enable or disable number and boolean coercion.
Use the output directly in a script, test fixture, or database seed.
Turn a spec table in a README into a JSON fixture for your test suite.
Extract product, inventory, or config tables from Markdown specs into JSON pipelines.
Pull a table out of a doc to validate against another source of truth.
Convert content tables in Markdown posts into JSON for faceted filtering UIs.
Extract example response tables from API docs into JSON sample payloads.
Yes. Free forever, no account required.
Standard GFM pipe tables with a header row and a separator row of dashes.
Yes. Switch the 'Table' dropdown from 'First only' to 'All tables'.
Yes, optionally. Numbers and booleans are coerced by default; toggle off to keep every value as a string.
No. Runs 100% in your browser.
