Information about CSV and JSON file formats

Full name CSV - Comma-Separated Values JavaScript Object Notation
File extension .csv .json
MIME type text/csv application/json
Developed by Informational RFC Douglas Crockford
Type of format multi-platform, serial data streams
Description In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The comma as a field separator is the source of the name for this file format. JSON (JavaScript Object Notation) is a lightweight textual data interchange format. JSON contains a small set of formatting rules for representing structured data. Various applications use it as an alternative to XML file format.
Technical details The CSV file format is not standardized. The basic idea of separating fields with a comma is clear, but that idea gets complicated when the field data may also contain commas or even embedded line-breaks. CSV implementations may not handle such field data or use quotation marks to surround the field. The data in JSON files are stored in plain text file format. Therefore, its contents can be viewed in any simple text editor. You can also convert JSON to pdf and some other formats with our converter.
