GUID generation is relatively simple. It is a system that is used to generate unique values without having to keep track of the IDs you have generated previously. Although duplicates are possible, it is so incredibly unlikely, that it makes GUIDs an efficient and robust unique identifier. The tool below will allow you to generate a huge number of GUID values at random. Enter the number of values you want and it will generate them for you.

Verifying GUID Formatting

If you are looking to verify that the GUID values you are using are correct, you can check out my GUID validation tool. You can input a value and it will let you know whether it is a valid value or not. This can be useful when you have obtained a value from somewhere and want to be sure what it is. Sometimes it is possible to get a value for a GUID that does not have dashes. This is common and normal. The values are valid, just harder to read and harder to manually verify.
