Free Text Tools Online: Word Counter, Case Converter, JSON Formatter and More
Writers, students and developers all fight the same small text battles — an essay that must be exactly 500 words, a paragraph typed in ALL CAPS by mistake, a list full of duplicate lines, a block of JSON nobody can read. ToolNest's text tools finish each of these jobs in seconds, free, directly in your browser.
For writing and essays
The Word Counter counts words, characters, sentences and reading time as you type — essential for essays, applications, speeches and social media posts with limits. Typed in the wrong case? The Case Converter switches between UPPERCASE, lowercase, Title Case and Sentence case in one click. Clean up messy pasted text with Remove Extra Spaces, flip text with Text Reverse, listen to it read aloud with Text to Speech, and preview formatted writing (syntax help: the Markdown Guide) in the Markdown Preview.
For cleaning lists and data
Email lists, name lists and copied data always carry repeats — Remove Duplicate Lines deletes them while keeping the order. Sort Lines arranges any list alphabetically or in reverse, and Find and Replace changes a word everywhere in a long document at once. Need dummy text for a design? The Lorem Ipsum Generator creates clean placeholder paragraphs.
For developers
The JSON Formatter beautifies and validates JSON so errors are easy to spot. The complete JSON reference lives on MDN Web Docs. The Encoder / Decoder handles Base64 and URL encoding, the Slug Generator turns post titles into clean URLs, and the Password Generator creates strong random passwords with a strength meter — generated on your device, never stored.
Common questions
