Frequently Asked Questions
Can I format code in different styles?
Yes, the SQL Formatter and other code tools support multiple formatting options and indentation styles.
Is regex testing case-sensitive?
The Regex Tester supports case-sensitive and case-insensitive matching, along with global and multiline flags.
Can I process multiple lines at once?
Yes. Most text tools operate on the whole input, so you can paste multi-line content and apply the operation to every line in a single pass.
Is there a character limit?
There is no fixed limit — the tools run in your browser, so the practical ceiling is your device memory. Very large inputs may slow down rendering.
