Frequently Asked Questions
What is JSON to CSV conversion?
JSON to CSV conversion transforms structured JSON data — arrays of objects, arrays of arrays, or a single object — into a flat, comma-separated table that spreadsheets like Excel and Google Sheets can open directly.
What is the difference between JSON and CSV?
JSON is a hierarchical, key-value format used in APIs and web applications. CSV is a flat, tabular format ideal for spreadsheets. Converting JSON to CSV makes API or database data easy to open in a spreadsheet.
How are nested objects and arrays handled?
When Flatten nested objects is enabled, nested objects are flattened into dot-notation columns such as address.city. Arrays and any values that can't be flattened are converted to their JSON string form so no data is lost.
What delimiter formats are supported?
This tool supports comma, semicolon, tab, and custom delimiters. Choose the one that matches the spreadsheet or system you're importing into.
Does this tool store my data?
No. All processing happens in your browser. Your JSON data is never sent to any server.
Is this converter free to use?
Yes, this JSON to CSV converter is 100% free with no limits, no sign-up, and no ads.
