How to Use This Tool

  1. Paste your CSV text into the input box, or copy it from a file and paste.
  2. The table renders automatically; the delimiter is detected from the first line.
  3. Click a column header to sort by that column; click again to reverse the order.
  4. Type in the filter box to show only rows containing your search term.
  5. Read the row count to confirm how many records matched your filter.

What Is a CSV Viewer?

CSV (comma-separated values) is the lowest-common-denominator format for tabular data: one record per line, fields separated by commas, with optional double quotes around values that themselves contain commas, quotes, or line breaks. The de-facto rules are written down in RFC 4180. Almost every spreadsheet, database, and analytics tool can read and write it, which is exactly why messy CSV is everywhere and why a quick way to look at one matters.

This viewer reads the text entirely on your device. It auto-detects whether fields are separated by commas, semicolons, or tabs by sampling the first line, then applies a full RFC 4180-style parser that respects quoted fields. The result is a real HTML table: click any column header to sort ascending or descending (numeric when both values are numbers, alphabetic otherwise), and type in the filter box to keep only rows that match.

Because nothing is uploaded, you can safely inspect exports that contain customer records, financial figures, or anything else you would not want leaving your machine. The grid is read-only — to change values, export and open the file in a spreadsheet app or use one of the other tools here.

Frequently Asked Questions

How large a file can it handle?
Parsing runs in your browser, so practical limits are device memory — tens of thousands of rows are fine, multi-hundred-MB files are not.
Which delimiters work?
Comma, semicolon, and tab are auto-detected from the first line, and you can override the choice manually if detection guesses wrong.
Can I edit the data here?
The grid is read-only for browsing. To change values, export to CSV or open the file in a spreadsheet app.
