CSV Preview turns pasted CSV (or TSV, semicolon- or pipe-separated) text into a readable table as you type. Quoted fields that contain the delimiter, a newline, or an escaped quote are parsed correctly, not just split on the delimiter character. When a table is wider than the screen, only the table scrolls horizontally inside its own border - the rest of the page stays put. Everything runs in your browser; nothing you paste is sent anywhere.

How to use it

  1. Paste CSV data into the text box.
  2. Pick the delimiter if it isn't a comma, and toggle "First row is header" to match your data.
  3. Scroll the table sideways if it's wider than your screen.

Frequently asked questions

Is my CSV uploaded anywhere?

No - parsing happens entirely in your browser as you type or paste. Nothing you enter is sent to a server.

Does it handle quoted fields and commas inside a cell?

Yes - fields wrapped in double quotes can contain commas, newlines, and escaped quotes ("") and are parsed correctly.

What if my data is tab- or semicolon-separated?

Pick Tab, Semicolon, or Pipe from the delimiter dropdown - it's not limited to comma-separated values.

What happens with a wide table that doesn't fit my screen?

The table sits in its own horizontally scrolling container, so wide data scrolls sideways instead of squeezing columns or breaking the page layout.

Can I turn off the header row?

Yes - uncheck "First row is header" if your data has no header row, and every row is treated as data with numbered columns.
