JSON to CSV Converter
Convert JSON arrays to CSV format instantly. Perfect for importing data into spreadsheets like Excel and Google Sheets.
About JSON to CSV Converter
Most APIs and many internal services emit JSON, but spreadsheets are still the universal tool for reviewing tabular data with non-technical teammates. This JSON to CSV converter bridges that gap. Paste an array of JSON objects, and the tool flattens the structure into rows and columns ready to open in Excel, Google Sheets, Numbers, or any data warehouse importer. Keys at the top level become column headers automatically.
It handles the edge cases that usually trip up naive conversions: nested objects flattened with dot notation, arrays inside fields serialized cleanly, and inconsistent shapes across records (where some objects have fields others do not) handled without dropping data. Typical uses include exporting search results, preparing data for finance or product reviews, and creating quick spot-check files from staging APIs before a release.
How to Use
Paste a JSON array of objects into the input editor.
Choose your preferred delimiter (comma, semicolon, or tab).
Click 'Convert' to generate the CSV.
Copy the result or download it as a .csv file.
Frequently Asked Questions
What JSON format does this tool accept?
A JSON array of objects, e.g. [{"name":"Alice"},{"name":"Bob"}]. Each object becomes a row, and each unique key across all objects becomes a column header.
Can I use a different delimiter?
Yes. You can choose between comma (,), semicolon (;), or tab as your delimiter. Semicolons are common in European locales where commas are decimal separators.
Is my data sent to any server?
No. All conversion happens in your browser. Your data stays on your device — even sensitive business data is safe to convert here.
Can it handle nested JSON objects?
Not directly. CSV is a flat format, so nested objects need to be flattened first (using dot notation like 'user.name') or stringified into a single cell. Pre-process complex JSON before converting.
