💡 A proper RFC 4180 parser — handles quoted fields, commas and line breaks inside quotes, and escaped quotes. With "first row is a header" on, you get an array of objects; off, an array of arrays. Everything runs in your browser.

APIs tips

🔌

Keep "first row is a header" on to get an array of objects keyed by column name — ideal for APIs.

🔢

Turn on type conversion so numbers and booleans arrive as real JSON types, not strings.

📋

Copy the JSON straight into a request body or fixture.

🔒

Data is parsed in your browser — never uploaded.
