UUID Generator not working? Here's how to fix it

Most issues are small and fixable in seconds. Work through these in order.

1. The tool won't load

Reload the page or open it in a fresh tab. If an extension blocks scripts, use private (incognito) mode — the tool needs JavaScript, which is on by default in every modern browser.

2. Nothing generates

Confirm a count is set to at least 1 and you've chosen a version. If the count is zero, there's nothing to show.

3. Copy doesn't work

Some browsers need permission to use the clipboard. Select the text and copy manually, or allow clipboard access in your browser settings.

4. It's the wrong version

Make sure you selected the version you need. v4 is random and v7 is time-ordered — pick the one that fits your use.

5. I can't select individual IDs

If generating a batch, use the per-row copy buttons if available, or select the one you need manually.

Still stuck?

Try a different current browser (Chrome, Firefox, Safari, Edge). Because the tool runs locally, a fresh environment usually resolves remaining edge cases.

Verdict

Most UUID problems are solved by a reload, a valid count, or granting clipboard permission.
