常见问题
Is my text sent to a server when I paste it?
Text processing happens in your browser. Tool code does not submit what you type or paste to a TOOLGRID processing endpoint.
Is there a text size limit?
There is no enforced limit. Performance depends on your browser and device. Most tools handle documents up to several megabytes of text without issues.
What is the difference between a text diff and a file diff?
The Text Diff Checker compares two blocks of text pasted directly into the tool, highlighting added, removed, and changed lines. For comparing files, paste their contents into the two input areas.
How do I convert text to a URL slug?
Open the Slug Generator, paste or type your title, and the tool produces a lowercase, hyphenated URL slug instantly. It strips punctuation, collapses spaces, and handles special characters automatically.
Can I use regex to find and replace text?
Yes. The Regex Tester lets you write a regular expression, test it against a sample, and see all matches highlighted in real time.
What does HTML escape do?
HTML escaping converts characters like <, >, &, and " into their HTML entity equivalents (<, >, &, ") so they display correctly inside HTML without being parsed as markup.
