Text Tools

Which tool should I use?

Word Count

For checking whether a passage fits a limit. It recounts as you type and reports six figures at once. The Chinese count covers Han characters only, excluding full-width punctuation; English words are matched with \b[a-zA-Z]+\b, so don't counts as two and bare numerals count as none.

Case Converter

Latin letters only. The mode worth understanding is Sentence case: it lowercases the whole passage first, then raises the letter after each full stop, so iPhone and API lose their capitals along the way. Choose Title case when proper nouns matter.

Full/Half Width

The mapping covers ASCII ! through ~, their full-width twins, and both kinds of space. Chinese punctuation such as 。 and 「」 falls outside that block and passes through untouched. This is for the full-width letters and digits that arrive with a paste from Word or Excel.

Line Deduplicator

For a list with one record per line — addresses, SKUs, keywords — where duplicates must go but the ordering must survive. It keeps the first appearance of each value, never sorts, and always drops blank lines.

Line Break Handler

The right choice when each line is correct and the damage is between lines: collapse runs of three or more blank lines into two, join everything onto one line, or translate between CRLF and LF. Note the division of labour — this one ignores what the lines say, the deduplicator ignores how they end. Text pasted from a PDF usually has to be rejoined here first.

Traditional/Simplified

The dictionary loads when you press Convert, so the first run pauses briefly. What happens is script conversion, not regional vocabulary substitution: 軟體 becomes 软体 rather than the mainland term 软件. Characters where one Simplified form maps to several Traditional ones are resolved correctly in both directions.

Shared limitations

• Windows line endings are normalised to LF the moment you paste, so finish with the LF → CRLF mode if the result goes back to a Windows toolchain.
• Only the script converter waits for a button; the other five recompute on every keystroke, which means no submit step and no undo. Keep your own copy of the original.
• The page offers text boxes and accepts no files. Rewriting happens in this tab's JavaScript, so the draft you paste is never sent anywhere. The page does separately load Google's advertising script, and that connection carries slot information rather than your text.
