What is CSV ↔ JSON Converter?
CSV (Comma-Separated Values) is a simple, widely-used format for tabular data — commonly used in spreadsheets and data exports. JSON is the standard format for data interchange in web applications. Converting between them is a common task when moving data between spreadsheets and APIs.
FAQ
Does this handle commas inside quoted fields?
Yes — standard CSV quoting with double quotes is supported, so fields containing commas won't break the conversion.
What JSON structure does CSV convert to?
Each CSV row becomes a JSON object, using the header row as keys. The result is a JSON array of these objects.
