Delimiter

💡 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.

TSV tips

↹

Data copied straight from Excel or Sheets is usually tab-separated — set the delimiter to Tab.

🧱

Great for quickly turning a pasted selection into structured JSON.
