JSON and CSV are both widely used for exchanging data, but they solve different problems. JSON represents structured and nested data, while CSV is designed around simple rows and columns.
What is JSON?
JSON stores data using objects, arrays, keys and values. It can represent nested structures and is commonly used by APIs, web applications and configuration systems.
What is CSV?
CSV stores tabular data as text. Each line normally represents a row, while separators divide fields into columns. It is easy to import into spreadsheet and database software.
JSON vs CSV: key differences
JSON supports nested objects and arrays and carries field names with the data. CSV is flatter and usually more compact for simple tables. JSON is generally better for application-to-application data, while CSV is convenient for spreadsheets, bulk imports and exports.
Which should you use?
Choose JSON when relationships and nested structures matter. Choose CSV when the data naturally fits a table and needs to be reviewed or edited in spreadsheet software. When you need both workflows, use the JSON to CSV Converter or CSV to JSON Converter.
