What's New in the Text Case Converter: Find & Replace, Sentence Counter, One-Tap Paste
A previous guide on this blog pointed out that the text case converter didn't yet have a sentence counter, a paste-from-clipboard button, or a proper find-and-replace field — and listed them as reasonable additions to watch for. All three have since shipped. Here's what each one does, with concrete examples of when to reach for it.
Find & Replace, with case-sensitive and whole-word matching
Quick answerA new Find & Replace section sits below the main converter. Type what you want to find, type the replacement, optionally check Case-sensitive and/or Whole word only, then click Replace all in text above — every match in the text box is swapped instantly, without leaving the page.
Before this, swapping a repeated placeholder or a misspelled name meant copying the text out to a separate editor, running find-and-replace there, then pasting it back in to re-run a case conversion. Now it's one panel on the same page. Say (as an example) you drafted a document referring to a project as "Client X" throughout, and the real client name just got approved — paste the draft in, type "Client X" in Find, the real name in Replace, and click the button once instead of hunting down every instance by eye.
The two checkboxes matter more than they look. Case-sensitive means "Cat" and "cat" are treated as different strings, so you can replace one without touching the other. Whole word only stops the tool from replacing a match that's just a fragment of a longer word — for example, replacing "art" with "craft" without this option would also change "start" and "smart"; turning it on limits the replacement to "art" standing on its own.
Whole-word matching, illustrated (example only)
Find / Replace
Whole word off
Whole word on
"cat" → "dog"
concatenate → condogenate
concatenate (unchanged)
"cat" → "dog"
the cat sat → the dog sat
the cat sat → the dog sat
Because it edits the same text box the case-conversion tabs read from, the order of operations is flexible: run Find & Replace first to fix a name or term, then switch to Title Case or Sentence case on the corrected text — or the reverse, whichever fits what you're doing.
The new sentence counter badge
Quick answerUnder the converted text, a new Sentences badge sits alongside the existing Words, Characters, and Lines badges, updating live as you type, paste, or edit. It uses the same sentence-boundary detection the Sentence case mode already relies on internally, now surfaced as a plain number.
The gap this closes is small but real: word and character counts tell you how long a text is, but not how it's structured. If you're checking whether a short bio reads as three tight sentences or one rambling run-on, or comparing a "before" and "after" edit to confirm you actually broke a wall of text into shorter sentences, the Sentences badge gives you that number without having to count periods by eye.
It updates the same way every other badge does — live, in the same result panel, with no button to click. Paste a paragraph in, and the Words/Characters/Lines/Sentences row updates together, all read from the exact text currently in the box.
One-tap paste from clipboard
Quick answerA new 📋 Paste from clipboard button sits in the toolbar above the text box, next to Sample text and the cleanup actions. Click it and the tool reads your device's clipboard and drops the content straight into the box — no need to click inside the box first or reach for a keyboard shortcut.
This one is aimed squarely at touch devices, where the normal paste flow — long-press, wait for the context menu, tap Paste — is slower than the keyboard shortcut most desktop users reach for automatically. On a phone or tablet, tapping one visible button instead is a small but noticeable improvement, especially if you're pasting text repeatedly while comparing a few different snippets.
Like every other action on this page, the paste button only reads what's already on your device's clipboard locally — nothing about that content is sent anywhere or logged.
It sits right next to the existing Sample text button, so the toolbar now covers both ends of getting text into the box: load a placeholder to try the tool, or pull in your own real text from the clipboard with the same one click.
Frequently asked questions
Where do I find the Find and Replace tool?
Scroll to the Find & Replace section below the converter (or click "Find & Replace" in the page navigation). Type the text you want to find, the replacement text, choose case-sensitive and/or whole-word options if needed, then click "Replace all in text above" — every match in the main text box is updated instantly, in your browser.
What does "whole word only" do in Find and Replace?
When "Whole word only" is checked, the tool only replaces matches that are a complete word on their own, not part of a longer word. For example, replacing "cat" with "dog" with this option on will change "the cat sat" but leave "concatenate" untouched, since "cat" there is inside a bigger word.
What does the sentence counter badge show?
Next to the Words, Characters, and Lines badges under the converted text, a Sentences badge shows a live count of sentence boundaries in your text — the same boundary detection the Sentence case mode uses internally, now surfaced as a number you can watch update as you type or edit.
How does the paste-from-clipboard button work?
Click the "Paste from clipboard" button above the text box and the tool reads your device's clipboard and drops the text directly into the box, without you needing to click inside it first or use a keyboard shortcut. This is mainly a convenience on touch devices, where opening a context menu to paste is slower than on desktop.
Do Find and Replace, the sentence counter, and paste-from-clipboard send my text anywhere?
No. All three run entirely in your browser using JavaScript, exactly like every other mode on the page. Find and Replace edits the text box directly, the sentence counter reads the same box to update its badge, and the paste button only reads your device's clipboard locally — nothing is uploaded or stored on a server.
Try the updated Find & Replace panel, watch the live sentence counter, and paste text with one tap — all free and processed entirely in your browser.
A note on this guide: the three features described above — Find & Replace with case-sensitive/whole-word options, the sentence counter badge, and the paste-from-clipboard button — reflect the tool as it exists at the time of writing. Examples involving specific words, placeholder names, or sample text are illustrative only, not statistics. This article is for general informational purposes.
