GUID Generator: Create v4 GUIDs in Four Output Formats
The GUID Generator creates version-4 GUIDs in Microsoft-style N, D, B, and P formats. Choose the format that matches your needs: N has 32 digits without hyphens, D is hyphenated, B uses braces, and P uses parentheses. Values are uppercase by default and use crypto-secure randomness. There is no seed option.
The GUID Generator creates version-4 GUIDs in Microsoft-style formats. Use it as a GUID generator when you need uppercase values in N, D, B, or P form, whether you are preparing test data or need identifiers for development work. The tool uses crypto-secure randomness and does not offer a seed option.
The format determines how each generated GUID is written. N contains 32 digits without hyphens, D uses the hyphenated form, B wraps the value in braces, and P wraps it in parentheses. Values are uppercase by default. Choose the representation that matches the format expected by the code or file where you plan to use the GUID.
GUIDs can be useful for identifying records, objects, or test fixtures. The different Microsoft-style representations express the same kind of identifier with different punctuation, so converting between them is mainly a matter of matching the format required by a tool or codebase. The generator produces version-4 GUIDs rather than allowing a seed to control the output.
The GUID Generator runs entirely in your browser. Your use of the tool does not send data to a server, and nothing is uploaded, stored, or sent elsewhere. It works offline once the page has loaded, so you can generate and copy GUIDs without an ongoing network connection.
This browser-based tool is useful for developers and DevOps engineers who need GUIDs for tests, fixtures, seed data, or other development tasks. Its format variants make it easier to get values in a familiar Microsoft-style representation, while the default uppercase output is ready to copy into your workflow.
Step 1: Set the available options for the GUIDs you need. The generator supports Microsoft-style N, D, B, and P formats.
Step 2: Choose the format that fits your destination: N has no hyphens, D is hyphenated, B adds braces, and P adds parentheses.
Step 3: Generate the version-4 GUIDs. They are uppercase by default and created with crypto-secure randomness.
Step 4: Copy the values you need for your code, tests, fixtures, or seed data.
Use case: Create GUID values for test cases and fixtures without typing sample identifiers by hand.
Use case: Generate a batch of GUIDs for seed data when a project needs multiple distinct-looking values.
Use case: Prepare GUIDs for development work using the N, D, B, or P format expected by your destination.
Use case: Use crypto-secure random GUIDs when you need values generated with randomness rather than guesses typed at a keyboard.
Use case: Create uppercase GUID values for examples or test data that should match the generator's default output.
Use case: Quickly copy generated GUIDs into code, configuration, or test resources instead of formatting them manually.
