About CSV
CSV (Comma-Separated Values) stores tabular data as plain text, with each line representing a row and commas separating columns.
The universal format for importing and exporting data between databases, spreadsheets, and analytics tools.
CSV has no official standard until RFC 4180 was published in 2005, decades after the format was already widely used.
💡 Despite the name, CSV files can technically use semicolons, tabs, or other delimiters instead of commas.
About JSON
JSON (JavaScript Object Notation) is a lightweight, human-readable format for structuring data as key-value pairs and lists.
The default format for APIs, configuration files, and passing structured data between web applications.
JSON was specified by Douglas Crockford in the early 2000s and is now defined by RFC 8259.
💡 Despite "JavaScript" in its name, JSON is language-independent and used by virtually every modern programming language.
