Text Tools - Free Online Tools
Manipulate, analyze, and transform text. Count words, compare differences, change case, sort lines, or find patterns. These tools handle the text processing tasks that come up constantly in development, writing, and data work.
Everything runs in your browser. No character limits for most tools. Your text stays private and never gets uploaded anywhere.
Available Tools
Regex Tester
Test regular expression patterns with real-time match highlighting. Supports all regex flags (g, i, m, etc.) and displays capture groups clearly.
Text Diff Checker
Compare two texts and highlight differences. Supports side-by-side and inline views with options to ignore whitespace and case.
Word & Character Counter
Count words, characters, sentences, and paragraphs. Includes reading time estimates and word frequency analysis.
Why Use Text Tools?
Text processing is everywhere in software development. Cleaning up data exports. Comparing file versions. Testing regex patterns. Converting between naming conventions.
You could write scripts for these tasks, but that takes time. Text tools give you immediate results for one-off jobs. Need to sort a list of 1000 items? Paste it in, click sort, done. Need to test a regex before adding it to your code? Test it first with real examples.
These tools are also useful outside of coding. Writers use word counters and diff checkers. Data analysts use line sorters and duplicate removers. Anyone working with text benefits from having these utilities handy.
