JSON (JavaScript Object Notation) is the standard data format for web APIs and modern applications. CSV (Comma-Separated Values) is the standard format for spreadsheets, databases and data analysis tools. Converting between these two formats is a very common developer and data workflow task.
The ToolForge JSON to CSV Converter handles this conversion instantly without any backend processing. You paste your JSON, click Convert and get a CSV file — all processing happens in your browser using client-side JavaScript.
The converter handles nested JSON objects by flattening them with dot notation. For example, a nested object like address.city becomes a column header address.city in the CSV. This makes it suitable for real-world API data that often contains nested structures.
Custom delimiter support means you can output semicolon-separated files for European Excel formats, tab-separated files for importing into specific databases, or standard comma-separated files for most tools.
