Random String Generator

Generate random strings for sample IDs, test data, mock tokens, and development notes directly in your browser.

Generated locally in your browser. Use these for test data, sample IDs, and non-sensitive labels; use a dedicated password manager for real passwords.

What this tool does

The Random String Generator creates one or more strings with configurable length, character sets, prefixes, and ambiguous-character filtering. It is intended for development and test data, not as a password manager.

Common use cases

Generate random strings for test data, sample identifiers, mock tokens, and developer documentation without uploading input.

Use Random String Generator when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.

How to use it

  1. Choose how many strings to generate and the length of each string.
  2. Select uppercase, lowercase, numbers, symbols, and optional prefix settings.
  3. Generate a fresh batch and copy the strings for test data, identifiers, or documentation.

Example workflow

Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.

Privacy note

Client-side only: random strings are generated in your browser and are not uploaded or stored. Do not paste or generate secrets here for account passwords.

FAQ

Is this random string generator a password manager?

No. It is designed for development test data, sample IDs, mock tokens, and labels. Use a dedicated password manager for real account passwords.

Can I exclude confusing characters?

Yes. Turn on the ambiguous-character option to remove characters like 0, O, 1, I, and l from generated strings.

Are generated strings uploaded?

No. Random strings are generated locally in your browser and are not uploaded or stored by ClearUtils.
