JSON/CSV Converter
? Frequently Asked Questions
How does JSON to CSV conversion work?
The tool flattens JSON objects into rows and extracts keys as column headers. Nested objects can be flattened with dot notation (e.g., 'user.name') or kept as JSON strings within CSV cells.
Can it handle nested JSON structures?
Yes, the converter can flatten nested objects and arrays using customizable delimiters. You can choose how deep to flatten and whether to expand arrays into multiple rows or keep them as values.
Does CSV to JSON create an array of objects?
Yes, by default it creates an array where each row becomes an object with column headers as keys. You can also choose alternative structures like nested objects or key-value pairs.
What CSV delimiters are supported?
The tool supports comma, semicolon, tab, and pipe delimiters. It can also auto-detect the delimiter from your CSV data and handle quoted fields that contain delimiter characters.
How are data types preserved during conversion?
The converter intelligently detects and preserves numbers, booleans, and null values. Strings with numbers remain as numbers in JSON, and empty CSV cells can be converted to null or empty strings.
Is my data safe and secure?
Yes, absolutely! This tool runs entirely in your browser. All data processing happens locally on your device - nothing is uploaded to our servers. Your files and data never leave your computer, ensuring complete privacy and security.
