Convert JSON to CSV.
Flatten a JSON array of records into a tidy CSV table you can open in Excel, Sheets or Numbers. Faithful, no data loss.
JSON to CSV: records into a table
This turns a JSON array of records into a spreadsheet-friendly CSV — the keys become the header row and each object becomes a row. It's the quickest way to open API output or an export in Excel, Google Sheets or Numbers, or to load it into a database.
What converts cleanly
An array of flat objects that share the same keys maps perfectly: [{ "name": "Ada", "age": 36 }] becomes a name,age header and one row per record. Values with commas, quotes or line breaks are automatically quoted so columns stay aligned.
The one limitation
A CSV cell can't hold a nested object or array — a spreadsheet has no concept of nesting. If a record contains nested data, flatten those fields first (for example address.city), then convert. Plain tabular JSON is the sweet spot.

JSON to CSV
This converts tabular data from JSON to CSV. Values, rows and columns carry over; a plain CSV file holds data only, so formulas, charts and cell styling are dropped — what you get is the data, cleanly structured.
