JSON to CSV

APIs return JSON; finance teams, analysts and marketers work in spreadsheets. That mismatch surfaces every time someone needs to review an export, build a pivot table or hand data to a colleague who has never opened a code editor. Converting JSON into CSV bridges the two worlds without writing a script.

The conversion flattens an array of objects into rows and columns, taking each key as a column header. It works cleanly when your data is a consistent list of records, which is exactly what most API list endpoints return. Deeply nested structures need more thought, because a nested object has no natural single cell representation and usually has to be flattened into dotted column names or handled separately.

The result opens directly in Excel, Google Sheets, Numbers or any database import tool. Because the conversion runs in your browser, customer records and other sensitive exports are not sent to a third-party service, which is often the deciding factor for anyone handling personal data.

How to use the JSON to CSV

1. Paste your JSON, ideally an array of objects with consistent keys.
2. Run the conversion to produce comma-separated output.
3. Check the header row matches the fields you expected.
4. Copy or download the CSV.
5. Open it in your spreadsheet application and confirm the columns line up.

Examples

• An analyst converts an API export of orders into a spreadsheet for a pivot table.
• A marketer turns a JSON list of campaign results into CSV to share with a client who works in Excel.
• A developer prepares a CSV import file for a system that cannot accept JSON.

Frequently asked questions

What JSON structure works best?

An array of flat objects that share the same keys. Each object becomes a row and each key becomes a column.

How is nested data handled?

Nested objects and arrays do not map naturally onto a single cell. Flatten them first, or accept that nested values may appear as serialised text.

What happens to commas inside values?

Values containing commas, quotes or line breaks are quoted so that spreadsheet software parses them correctly.

Is my data uploaded?

No. The conversion happens entirely in your browser.
