Frequently Asked Questions
The tool accepts JSON arrays of objects. Example: [{"name":"John","age":30},{"name":"Jane","age":25}]. Each object in the array becomes a row in the CSV, with object keys becoming column headers.
The tool parses your JSON, extracts all unique keys from all objects to create CSV headers, then converts each JSON object into a CSV row. All keys are included even if some objects don't have all keys.
Nested objects or arrays are converted to JSON strings within the CSV cell. For complex nested data, you may want to flatten your JSON before conversion.
The tool requires an array of objects. If you have a single object, wrap it in an array: [{"your":"object"}]. This will create a CSV with one data row.
The tool can handle large JSON files (millions of characters). For very large datasets, processing may take a few seconds but there's no hard limit.
No problem! The tool collects all unique keys from all objects and creates a CSV with all columns. Missing values will be empty in the CSV.
No! All processing happens in memory and no data is stored. Your JSON is processed and immediately discarded after conversion.
Yes! This tool is completely free to use for personal and commercial projects with no restrictions.
The tool properly handles Unicode characters, special symbols, and international text. Your data will be preserved exactly in the CSV output.
Absolutely! This is one of the most common use cases. Just copy the JSON response from your API and paste it into the tool.
