Character Frequency Counter

Summary

The Character Frequency Counter analyzes any block of text and produces a ranked frequency table showing how often each character appears. Results update in real time as you type or paste, with options to filter spaces, digits, and punctuation and to toggle case sensitivity. The export feature lets you copy the table as CSV for further analysis in a spreadsheet.

How it works

1. Paste or type text into the input area.
2. Apply filters to include or exclude spaces, digits, or punctuation.
3. Toggle case-insensitive mode to merge upper and lowercase counts.
4. The frequency table sorts by count descending by default.
5. Click any column header to re-sort the table.
6. Click Copy CSV to export the data to your clipboard.

Use cases
