How to generate datasets
Use this category when a test, import, form, or script needs sample values. The available generator makes cryptographically random passwords, strings, numbers, and UUIDs, or seeded synthetic records that can be recreated for another test run. It creates the data in your browser, with no upload.
Generate random values and test data
Random Data Generator handles random values and repeatable test fixtures. Its random modes make passwords, strings, numbers, and UUIDs. Test Data mode uses a seed, so you can generate the same synthetic records again.
- Use random passwords when a form or account flow needs varied credential-shaped input.
- Use random strings, numbers, or UUIDs when a script needs values with those types.
- Use seeded Test Data mode when a CSV or JSON fixture needs to remain consistent between runs.
Choose a dataset generator for the job
Open Random Data Generator when you need new values or records. Export the result as CSV or JSON for the next step. Use a seed when a fixture must match a previous run; use random values when each test case needs different input.
If a table already exists and needs inspection or changes, visit Dataset Tools. That category covers profiling, cleaning, reshaping, merging, and generating tabular data. This category produces new values and records.
Typical dataset generation jobs
- A developer testing a CSV importer can create sample records, export CSV, and feed that file into the import step.
- A QA tester checking a form can generate varied passwords, strings, numbers, or UUIDs and paste the results into separate test cases.
- A developer reproducing a failed test can use seeded Test Data mode, export JSON, and keep the same synthetic records for the next run.
- A technical writer documenting an API can export JSON values for an example request.
Frequently asked questions
How do I generate datasets in a browser?
Open the Random Data Generator page, choose the needed kind of data, and export the result as CSV or JSON. The generator creates the dataset in your browser, with no upload.
What can a random data generator create?
Random Data Generator can create cryptographically random passwords, strings, numbers, and UUIDs. It also includes seeded Test Data mode for reproducible synthetic records.
Can I create reproducible test data?
Yes. Switch to seeded Test Data mode and generate the synthetic records again when you need the same test fixture.
Should I use Dataset Generate Tools or Dataset Tools?
Use Dataset Generate Tools when you need new random values or synthetic records. Use Dataset Tools when you already have tabular data and need to profile, clean, reshape, or merge it.
