JSON Data Table Viewer

Paste a JSON array of objects to view it as a sortable, filterable table. Search across every cell, sort by any column, and export the visible rows as CSV. Everything runs in your browser — nothing is uploaded.

About this tool

Turns a raw JSON array into a readable data table. Nested objects are flattened one level deep into parent.child columns, rows with different keys are merged into a single union of columns, sorting is numeric-aware, and the CSV export properly quotes fields containing commas, quotes, or newlines — so it opens cleanly in Excel or Google Sheets.

Your data never leaves the page — parsing, filtering, sorting, and CSV generation all happen locally in your browser. There is no server, no upload, and no tracking of tool inputs.
