Textarea Checker is a Chrome add-on developed by Irina Ivanova. This free tool is designed to help web testers and developers check if special symbols in textarea HTML fields are being processed properly.

Please note that this is a dead project and is no longer supported. Therefore, there is no guarantee that it will work on the latest versions of browsers.

With Textarea Checker, users can easily check or uncheck options to test different values and titles in textarea fields. The result of the test will be automatically copied into the clipboard for easy access.

Additionally, hot keys are available for quick navigation, including the ability to check or uncheck all values by pressing the number 0.
