String Utility
A multi-function string toolkit that shows live character, word, and line counts and applies common text transforms to your input.
Example
Input:
hello WORLD
from toolstack
After clicking Remove extra spaces then Title Case:
Hello World
From Toolstack
The stats line shows: Characters, Words, and Lines updating live as you type.
How it works
Type or paste text into the box to see live character, word, and line counts. Click a transform button (UPPERCASE, lowercase, Title Case, Reverse, Trim, Remove extra spaces) to apply it in place.
Good to know
String Utility is a single-box text workbench that combines a live counter with six one-click transforms. As you type or paste, it reports the character, word, and line count of your text, and lets you rewrite that text in place using UPPERCASE, lowercase, Title Case, Reverse, Trim, or Remove extra spaces. It's aimed at developers, writers, editors, and anyone who needs to quickly clean up or reshape a snippet without opening a code editor or spreadsheet.
Reach for it when you're pasting copy that has uneven spacing, fixing the casing of a heading or a list of names, checking whether a message fits a length budget, or sanitizing data copied out of a PDF or web page before pasting it somewhere stricter. Because every transform rewrites the same box, you can stack them, for example squeezing extra spaces first and then applying Title Case to get clean, evenly capitalized output.
Read the stats line under the box as three independent measures. Characters counts every character including spaces and line breaks; words are whatever is separated by whitespace, so runs of multiple spaces still count as one gap; and lines equal the number of line breaks plus one, meaning a single unwrapped paragraph reads as one line and an empty box reads as zero. The status message below the buttons confirms which action ran, which is helpful when a transform produces no visible change.
A few practical notes worth knowing:
- Title Case capitalizes the first letter of every word and lowercases the rest, so deliberate styling like "iPhone" or "API" will be flattened to "Iphone" and "Api" and may need manual fixing.
- Reverse works on whole characters in order, which is great for quick string puzzles but will scramble multi-line text and any direction-sensitive content; transforms are not undoable, so copy your original first if it matters.
Frequently asked questions
How are words and lines counted?
Words are counted by splitting the text on any run of whitespace, so multiple spaces between words still count as one separator. Lines are counted by the number of line breaks plus one (an empty box shows zero).
What does "Remove extra spaces" do exactly?
It collapses any run of spaces or tabs within each line down to a single space and trims leading/trailing spaces, while preserving your line breaks. Use Trim if you only want to remove whitespace from the very start and end of the whole text.
Is my data uploaded anywhere?
No — this tool runs entirely in your browser. Your input never leaves your device and it works offline once loaded.
Is it free?
Yes, completely free with no sign-up and no limits.
People also ask
What is the difference between Trim and Remove extra spaces?
Trim only removes whitespace from the very start and end of the entire text and leaves everything in between untouched. Remove extra spaces works on every line, collapsing runs of spaces or tabs down to a single space and trimming each line's ends, while keeping your line breaks.
Does the character count include spaces and line breaks?
Yes. The character count reflects the raw length of the text, so every space, tab, and line break is counted along with visible characters.
Can I undo a transform after I click a button?
There is no built-in undo; each transform rewrites the text box in place. To recover the original, paste it again or copy it somewhere safe before applying changes.
Why does Title Case change words like 'iPhone' or 'NASA'?
Title Case capitalizes the first letter of each word and forces every other letter to lowercase, so intentional mixed-case or all-caps words are normalized. You would need to re-fix those by hand after applying it.
How does the tool count words if I use multiple spaces or tabs between them?
Words are determined by splitting on any run of whitespace, so two spaces, a tab, or a newline between words all count as a single separator. Extra spacing does not inflate the word count.
Is there a limit on how much text I can paste?
There is no enforced limit imposed by the tool itself, since it runs locally in your browser. Very large inputs are bounded only by your device's memory and browser performance.
Does Reverse flip the order of lines or just characters?
It reverses the entire text character by character, including line breaks, rather than reversing line order. As a result, multi-line text will be turned around end to end.
Will my pasted text be sent to a server?
No. All counting and transforming happens in your browser using JavaScript on the page, so the text stays on your device and the tool keeps working offline once the page has loaded.
