JSON to CSV Converter - Transform JSON Data for Excel and Sheets

JSON is the standard format for APIs and modern applications, but spreadsheet tools (Excel, Google Sheets) work best with CSV. Converting JSON to CSV lets you analyze, filter, and visualize data in a spreadsheet.

Handling Nested JSON

JSON can have nested objects and arrays. Flat CSV can't directly represent nesting. Common strategies: flatten dotted keys (user.name), skip nested arrays, or convert nested objects to JSON strings in a single CSV cell.

JSON to CSV Step-by-Step

1. Prepare a JSON array of objects (e.g., a list of users)
2. Determine the full set of columns (union of all object keys)
3. Write the header row (column names)
4. Write each object as a row, filling missing keys with empty values
5. Download as .csv for Excel or Google Sheets
