What Is CSV and When Is It Used?
CSV (Comma-Separated Values) is one of the oldest and most universally supported data formats. It is used for spreadsheet exports, database dumps, data science datasets, bulk imports, and any scenario where tabular data needs to be shared between tools.
Our CSV tools let you convert tabular data to and from JSON, XML, YAML, and HTML — and handle character escaping to ensure your CSV data is safe when embedded in other formats.

Frequently Asked Questions
What is the difference between CSV and TSV?
CSV uses commas as delimiters; TSV uses tabs. TSV is useful when field values themselves contain commas, avoiding the need for quoting.
How does CSV to JSON conversion work?
The first row of the CSV is treated as the header (key names). Each subsequent row becomes a JSON object, with values mapped to the corresponding header keys.
Why do I need to escape CSV fields?
Fields containing commas, double quotes, or newlines must be escaped or quoted to prevent parsers from misreading the structure of the file.
Can I convert CSV to an HTML table?
Yes. Our CSV to HTML converter generates a properly structured HTML table with a <thead> header row and <tbody> data rows, ready to embed in any web page.
