Text Formatter

Text to clean up

Letter case

Whitespace

Convert tabs to 4 spaces

Trim trailing whitespace

Collapse runs of spaces into one

Applies anywhere in the line, including leading indentation, which gets collapsed to a single space too. Do not use this on code.

Collapse 2+ consecutive blank lines into one

Line endings

Paste some text and the result appears here.

Normalize letter case, tidy up trailing whitespace and tabs, collapse repeated blank lines, and unify line endings. This is a different tool from "Line tools" (dedupe/sort) and "Fullwidth/halfwidth conversion" — it works on the character sequence within a line.

FAQ

I want to remove duplicate lines.

Use "Line tools" instead — operations on the set of lines (dedupe, sort, fully removing blank lines) live there.

I want to convert fullwidth/halfwidth characters.

Use "Fullwidth/halfwidth conversion" — it converts by character type (letters, katakana, symbols) separately.
