Frequently Asked Questions About JSON to CSV Conversion
Why convert JSON to CSV?
CSV is a universal format supported by Excel, Google Sheets, and other spreadsheet applications. Converting JSON to CSV makes data easier to work with in traditional office software and databases.
What JSON structures are supported?
The converter supports JSON arrays of objects (most common) and single JSON objects. Each array element becomes a row, and object properties become columns.
How are nested objects handled?
Nested objects and arrays are converted to JSON strings within the CSV cell. This preserves the data but displays it as a formatted JSON string in the cell.
What about special characters?
Special characters, commas, and quotes are properly escaped using CSV standards. String values containing these characters are wrapped in quotes with internal quotes doubled.
Can I convert CSV back to JSON?
Yes! Use our JSON Formatter with CSV data pasted and formatted, or use a dedicated CSV to JSON tool. Our converter focuses on JSON to CSV transformation.
Is the conversion happening locally?
Absolutely! All JSON to CSV conversion happens entirely in your browser. Your data never leaves your computer and is never sent to any server.
