CSV Viewer

Data

Parse and view CSV files as a table or JSON with delimiter detection

Drop in a CSV export from a spreadsheet or database dump and it renders as a sortable table immediately, or flip to JSON view when what you actually need is data to paste into a script or API payload rather than something to eyeball. Delimiter detection samples the first few lines and guesses the most consistent separator, with a manual override for files that use semicolons or tabs and get misdetected. Quoted fields containing embedded commas, newlines, or escaped quotes are handled per standard CSV quoting rules (RFC 4180), not just naive comma-splitting. It works well up to a few MB in the browser since the whole file loads into memory; beyond that, a script with a streaming CSV parser is the better tool. The file itself never leaves your machine.

How to use CSV Viewer

  • 1.Paste or upload a CSV export from a spreadsheet or database dump to instantly view it as a sortable table.
  • 2.Switch to JSON view when you need to copy the data into a script or API payload instead of a spreadsheet.
  • 3.Use the delimiter override when a file uses semicolons or tabs instead of commas and auto-detection guesses wrong.

Frequently asked questions

Is my CSV file uploaded to a server?
No, parsing happens entirely in your browser — the file never leaves your machine.
How does delimiter detection work?
The tool samples the first few lines and picks the most consistent separator (comma, semicolon, or tab), but you can override it manually if it guesses wrong.
Can it handle quoted fields with embedded commas?
Yes, the parser follows standard CSV quoting rules (RFC 4180), including quoted fields that contain commas, newlines, or escaped quotes.
What's the largest file it can handle?
It works well for files up to a few MB in the browser; for very large CSVs, use a script with a streaming CSV parser instead since the whole file is loaded into memory.
