About the Character Frequency Counter

Frequency analysis is the classic first move against substitution ciphers — in English text "e" dominates at roughly 12%, so the most common symbol in a ciphertext is a prime suspect. It is just as handy for everyday work: spotting stray characters in a data export, checking whether a string is ASCII-clean, or seeing which punctuation a writer overuses.

Every distinct character gets a row with its raw count and its density — the percentage of the total it accounts for — plus a small share bar for visual scanning. Toggle spaces on to include them (shown as ␣) or off to focus on visible glyphs.

How to use it

  1. 1Type or paste the text you want to analyze.
  2. 2Switch "Include spaces" on or off depending on your analysis.
  3. 3Read counts and percentages in the table, or copy it as TSV for a spreadsheet.
