JSON to Spreadsheet Online

Paste a JSON array of objects and convert it into a live, editable spreadsheet. Nested keys are automatically flattened into dot-notation columns. Numbers, strings, and booleans are preserved.

How JSON flattening works

When you paste a JSON array of objects, we extract every unique key to create column headers. Nested objects are flattened using dot notation. For example, { "user": { "name": "Alice" } } becomes a column called user.name.

Arrays within objects are joined with commas into a single cell value. Numbers stay as numbers (so you can use spreadsheet formulas on them). Booleans are preserved as-is. Null values become empty cells.

The resulting spreadsheet is fully editable. You can add formulas, change formatting, sort columns, and share the link with anyone. No software to install, no account required to view.

Common use cases

API response inspection

Paste a JSON API response to quickly visualize and share the data in spreadsheet format.

Database exports

Export a collection from MongoDB or Firestore, paste it here, and get a spreadsheet for non-technical teammates.

Log analysis

Convert structured log entries into a spreadsheet for filtering, sorting, and pattern detection.

Configuration review

Turn JSON config files into a readable table to review with your team.

Automate this with our API

Convert JSON to spreadsheets programmatically. One POST request creates a spreadsheet and returns a shareable URL. Ideal for automated reporting, data pipelines, and AI agent integrations.
