How to use Generate a Random GUID
- 1. Set how many GUIDs. Enter How many UUIDs to decide how many globally unique identifiers the generator produces, from a single value to a large batch for seeding test records.
- 2. Choose the letter case. Turn on Uppercase if the destination system expects GUIDs in capital hex digits, or leave it off for the more common lowercase convention.
- 3. Set a separator. Choose Separator, typically a newline, so each GUID lands on its own line ready to paste into a database seed script or config file.
- 4. Copy the GUIDs. Copy the generated identifiers directly into your project. Each one follows the standard 8-4-4-4-12 hyphenated format.
When to use Generate a Random GUID
Generate a Random GUID produces standard-format globally unique identifiers on demand, the same 8-4-4-4-12 hex pattern used across Windows APIs, databases, and countless config files. It is aimed at anyone who needs placeholder or test IDs quickly.
- Seeding a database with test records. A developer setting up a test database with a GUID primary key column needs a batch of valid-looking identifiers to fill sample rows before real data arrives.
- Filling in a config file template. Someone configuring a Windows COM component or a .NET project file needs a placeholder GUID in a manifest before the real one is assigned.
- Naming temporary resources in a cloud script. An engineer writing an infrastructure script wants a unique suffix for a temporary storage bucket or queue name to avoid collisions during testing.
- Mocking API responses in documentation. A technical writer building example API responses wants realistic-looking GUID values for resource IDs without exposing any real identifiers from production.

About the Generate a Random GUID tool
Generate a Random GUID does its work locally, right in the browser. Quickly generate random GUIDs. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Random Tools collection on EditSafely, a set of 120 small, focused Random utilities that share the same instant, private workspace.
You can shape the output with 3 settings, including How many UUIDs, Uppercase and Separator, and the result refreshes the moment you change one. 2 worked examples further down the page show exactly what the tool produces for real inputs.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
