How it works

Paste any JSON: an array of objects becomes rows, a single object becomes one row, and primitives are wrapped automatically. Tick flatten nested objects to expand address.city style keys into their own columns with dot notation.

Click any column header to sort, type in the search box to filter rows, then export the full dataset to CSV or copy a clean HTML table for your docs.

Private by design

Parsing runs on the browser's native JSON parser, so even large API responses render fast and nothing is uploaded. Only the first 2,000 rows are drawn for speed; CSV export always includes everything.

Handy for inspecting API responses, log dumps, config files and spreadsheet-style data without opening a code editor.

JSON Table Tools FAQs

What JSON shapes does it accept?
Arrays of objects work best, one row per object. A single object becomes one row, and arrays of primitives become a one-column table. Nested objects can be flattened into dot-notation columns.
How do I export to CSV?
Press Export CSV after rendering. Values containing commas, quotes or newlines are properly quoted, so the file opens cleanly in Excel or Google Sheets.
Can I sort by a column?
Yes. Click any column header to sort ascending, click again for descending. Numbers sort numerically, everything else alphabetically.
Is my JSON data uploaded?
No. It is parsed with your browser's native JSON parser and never leaves your device, so API keys or private records in the data stay private.
Why did it say invalid JSON?
The message includes the parser's exact complaint and position. Common culprits are trailing commas, single quotes instead of double quotes, and unquoted keys.
