Text Tools

Diff, count, sort, de-duplicate and transform text without leaving the page.

Case Converter Converts text between the nine cases people actually need, including the four identifier conventions.
Character Frequency Counter Counts every distinct character with its share and its Unicode code point, which is how you find the invisible one.
Duplicate Line Remover Removes repeated lines while keeping the original order, or shows you only the duplicates instead.
Find and Replace Replaces every match across a block of text, by plain string, whole word or regular expression.
Line Numberer Adds a number to the front of every line, starting wherever you like, with optional zero padding.
Line Sorter Sorts lines alphabetically or in natural numeric order, so item2 comes before item10.
Slug Generator Turns a list of titles into URL slugs, folding accents and flagging any two that would collide.
Text Diff Compares two blocks of text line by line and lists exactly what was added and removed.
Whitespace Cleaner Strips trailing whitespace, collapses runs of spaces, converts tabs and tidies blank lines.
Word Counter Counts words, characters, UTF-8 bytes, lines, sentences and paragraphs, and estimates reading time.
