What is JSON to CSV conversion?
JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. Converting JSON to CSV creates a flat, tabular file that can be opened in spreadsheets like Google Sheets, Excel, or imported into databases.
When to convert?
Convert JSON to CSV when you need to analyze API data in a spreadsheet, import JSON records into a database, or share data with people who prefer tabular formats. CSV is universally supported by spreadsheet apps and data tools.
Frequently asked questions
Is my data safe when converting JSON to CSV?
Yes. The conversion runs entirely in your browser. Your JSON data is never sent to any server.
What JSON formats are supported?
The converter accepts a JSON array of objects (most common) or a single JSON object. Each object's keys become CSV column headers.
What happens with nested JSON objects?
Nested fields are flattened into the CSV output. Simple nested values are serialized as strings in the CSV cells.
Can I convert large JSON files?
Yes. Since processing happens in your browser, there are no server-imposed limits. Very large files may take a moment depending on your device.
