Open generatorHow to use the Hublabs generators and formatters
This category gathers tools for people who build, test, and document software: sample data generators, code formatters, and decoders.
The tools process what you type in your own browser. Even so, prefer fictitious data: real passwords, tokens, and documents should not be pasted into online tools.
They are useful for filling a layout with placeholder text, creating fictitious data for a test sign-up, reviewing an API response, building a schedule, or testing a regular expression before putting it in your code.
Which tool to choose
- Test data — passwords, UUID v4, fictitious CPF and CNPJ, Lorem Ipsum, and QR Code.
- Formatters — JSON, SQL, XML, and Markdown with preview, to make text and code readable.
- Encoding — Base64, URL encoding, SHA hashes, and JWT token reading.
- Development support — Cron expressions, regex tester, and color picker.
Good practices
- Longer passwords with varied character types are harder to guess. Keep the generated password in a password manager, not in loose notes.
- Generated CPF and CNPJ numbers follow the check-digit rule but do not belong to anyone. Use them only in test and demo environments.
- A hash is a one-way digest: it is meant for comparing content, not for recovering the original text. Base64 is only an encoding and can be reversed by anyone.
- Formatting JSON, SQL, or XML only changes the visual layout, not the content. The JSON and XML formatters also point out syntax errors to fix before you use the result.
Generated documents are fictitious and meant for testing only; decoding a token does not validate its signature.
