JSON & CSV Toolkit

Pasting production API responses or internal spreadsheet exports into random online formatters risks exposing customer data to third-party logs. This toolkit runs entirely inside your browser tab to validate JSON syntax, pretty-print or minify payloads, flatten nested JSON objects into clean CSV columns, and parse CSV files back into typed JSON arrays.

Data Runs entirely in your browser. Your data is never uploaded.
Actions:

Paste raw JSON or CSV data below.

Copy to clipboard or download as a file.
