About JSON to CSV
You have a JSON array from an API or a database export, but the analyst, spreadsheet, or import tool on the other end only speaks CSV. Flattening nested objects and lining up columns by hand is tedious and error-prone, especially once you have hundreds of records. This converter does the mapping for you so your data lands in rows and columns ready to open in Excel, Google Sheets, or any CSV importer.
Paste a JSON array of objects and the tool reads each object's keys to build the header row, then writes one CSV line per item, quoting and escaping values as needed. It runs free in your browser with no signup, so your data stays on the page and you get the result instantly. Best results come from a flat array of similarly shaped objects.

FAQ
Does it handle nested JSON objects?
It works best with a flat array of objects. Deeply nested fields may be stringified or flattened, so simplify nested structures first for the cleanest columns.
What if my objects have different keys?
The header is built from the keys it finds across records. Objects missing a key will leave that cell empty, so consistent shapes give the tidiest output.
Are commas and quotes inside values handled?
Yes. Values containing commas, quotes, or line breaks are wrapped in quotes and escaped so the CSV stays valid.
Is my data uploaded anywhere?
Conversion happens in your browser. Nothing is stored or shared, which suits sensitive or internal datasets.
Can I use JSON to CSV on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
