JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate.
CSV (Comma-Separated Values) is a simple file format used to store tabular data in plain text format, with values separated by commas.
While CSV files are lightweight and widely compatible for tabular data, they lack the nested structure and data typing capabilities that JSON provides.
JSON files can represent complex data hierarchies, include arrays and objects, and support different data types like strings, numbers, booleans, and null.
Converting from CSV to JSON allows you to take advantage of JSON's flexibility for data interchange and integration with modern web applications and APIs.
Converting CSV to JSON involves transforming flat tabular data into a structured object or array format.
JSON conversion tools use libraries like JSON.parse/stringify, pandas, or other data processing libraries to create properly structured JSON objects from raw CSV data.
Advanced converters can auto-detect CSV delimiters (commas, tabs, or semicolons) and map column headers to JSON property names.
During conversion, CSV column headers typically become JSON property names, with each row becoming an object in a JSON array.
JSON is the standard data format for REST APIs and web services, making it ideal for use in web applications and data exchange between client and server.
An online CSV to JSON converter allows you to quickly transform CSV data into JSON format without installing specialized software. It's convenient for converting tabular data from any device with a browser.
