About This Tool
JSON and CSV are two of the most common data formats. JSON is great for APIs and complex data structures, while CSV is perfect for spreadsheets and simple tabular data.
When converting JSON to CSV, arrays of objects become rows with object keys as column headers. Nested objects are flattened with dot notation (address.city becomes a column).
CSV to JSON conversion treats the first row as headers and creates an array of objects. Each subsequent row becomes an object with header names as keys.
Custom delimiters are supported for CSV - tabs, semicolons, or any character. This handles regional CSV variations and TSV files.
