JSON to CSV Converter

The JSON to CSV Converter flattens an array of JSON objects into a spreadsheet-ready CSV that you can download with a single click. Nested objects are flattened using dot-notation keys, so even a moderately structured payload becomes a clean, predictable set of columns that opens neatly in any spreadsheet program.

Analysts and developers use it to get JSON — whether an API response or a data export — into a spreadsheet for review, reporting or sharing with colleagues who do not work with raw JSON. An array of flat objects converts most cleanly, with each object becoming a single row and each key becoming a column header.

The conversion runs in your browser, so your data is never uploaded to a server. With nothing to install and no account, you can turn a block of JSON into a downloadable CSV file privately and instantly, ready to drop into a report.
