Convert JSON data to CSV format for importing into spreadsheets, databases, or legacy systems that expect tabular data. Takes JSON array of objects and produces formatted CSV with headers from object keys. Handles nested objects with dot notation.
Paste a JSON array of objects into the input field. The tool automatically extracts all unique property names as column headers and converts each object into a CSV row. Nested objects are flattened using dot notation. You can customize the delimiter, choose whether to include headers, and download the result as a .csv file compatible with Excel and Google Sheets.
JSON-to-CSV conversion is needed when exporting API data for analysis in spreadsheet applications, creating reports from database query results, importing structured data into SQL databases via CSV import tools, sharing data with non-technical stakeholders who work in Excel, generating data exports for business intelligence tools, and creating downloadable reports in web applications.
The converter scans all objects in the array to build a complete set of column headers, handling cases where different objects have different properties. Nested objects are flattened with dot-notation keys (e.g., user.name). Array values are serialized as JSON strings within CSV cells. Values containing commas, quotes, or newlines are properly escaped by wrapping in double quotes with internal quotes doubled, per RFC 4180.
Paste a JSON array of objects (e.g., [{"name":"Alice","age":30}]) into the input. The tool extracts all unique keys as column headers and outputs each object as a CSV row.
Nested objects are flattened using dot notation. For example, {"user":{"name":"Alice"}} becomes a column named 'user.name' with value 'Alice'.
