Paste a JSON array and download a clean CSV file ready for spreadsheets.

Convert a JSON array of objects or arrays into a CSV file. Pick the delimiter and whether to include a header row. Handles unioned keys across rows so no column is silently dropped.

- **Category:** Text
- **Availability:** Free to use without an account, email address, subscription, or payment.
- **Input:** Entered in the browser

## How it works

1. Paste your JSON array into the editor.
2. Pick the delimiter and whether to include a header row.
3. Process and download the.csv file.

## Use cases

- Turn an API JSON response into a CSV for a spreadsheet.
- Export a JSON dataset as CSV for a business analyst.
- Convert MongoDB or Firebase output to CSV for Excel.
- Prep a JSON list for import into a CRM that expects CSV.

## Frequently asked questions

### What JSON shape do I need?

A top-level JSON array. Each item can be an object (keys become column headers) or an array (positional values). Mixed objects/arrays in one input aren't supported.

### What if my objects have different keys?

We take the union of all keys across the array, so a column that only appears in later objects still becomes a CSV column. Empty cells are written for rows that don't have that key.

### Are special characters quoted correctly?

Yes. Values containing the delimiter, quotes, or line breaks are wrapped in quotes and internal quotes are doubled (the standard RFC 4180 behaviour).

### Is there a size limit?

Up to 2 MB of JSON per conversion, plenty for most real-world exports.
