JSON to CSV Converter
Convert a JSON array of objects into CSV. Nested objects are flattened with dot notation, columns are unioned across all records, and output opens directly in Excel or Google Sheets.
About this JSON to CSV Converter
API responses rarely match spreadsheet shape — this converter unions the keys of every record so no column is lost, flattens nested objects into dotted column names, and JSON-stringifies arrays so nothing breaks the row. Downloads include a UTF-8 BOM so Excel opens accents and ₹/€ symbols correctly.
