📊 JSON Table Viewer
Paste JSON and browse it as a sortable table, then export CSV.
Paste a JSON array of objects (a single object works too).
🔒 Files never leave your browser. Everything is processed locally on your device.
How to use
- Paste a JSON array of objects into the box.
- Click Render Table — click any column header to sort.
- Download the data as CSV whenever you're ready.
FAQs
What if the objects don't all have the same fields?
All fields are collected into columns and rows that lack a field show an empty cell — nothing is dropped.
Is there a size limit?
For speed, the on-screen table caps at the first 500 rows. The CSV download includes every row, no cap.
Is my data uploaded anywhere?
No. Rendering happens entirely in your browser — your data is never sent to any server.
