Does this tool count uppercase and lowercase letters separately?

By default the counter is case-sensitive, so "A" and "a" are counted separately. Toggle the "Case-insensitive" switch to merge uppercase and lowercase into a single row.

Can I exclude spaces and punctuation from the count?

Yes. Use the filter checkboxes to include or exclude spaces, digits, and punctuation marks independently, so you can focus on just the letters.

Is there a character limit for the input text?

There is no server-side limit because all processing happens in your browser. Very large texts (millions of characters) may take a moment on older devices.

What does the percentage column represent?

The percentage shows each character's count divided by the total number of characters currently being analyzed (after applying your filter settings).

Can I export the results?

Yes. Click "Copy CSV" to copy a comma-separated version of the table to your clipboard, ready to paste into Excel, Google Sheets, or any spreadsheet tool.

What is the most common letter in English?

In typical English text the letter "e" is the most frequent at about 12.7%, followed by "t" (≈9.1%) and "a" (≈8.2%). Paste your own text above to see how its letter distribution compares to these standard English frequencies.
