Random String Generator
Generate random strings for test data, mock tokens, sample IDs, labels, and documentation examples 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.

Random string generator workflow tips
Use this tool when you need quick sample identifiers, mock tokens, fixture values, temporary labels, or random alphanumeric strings that do not need to be saved by ClearUtils. Generation happens locally in your browser.
Generate test IDs and fixture values
Add a prefix like user_, order-, or fixture_ so generated strings are easier to recognize in spreadsheets, docs, and QA notes.
Avoid confusing characters
Keep ambiguous-character filtering on when people need to read or retype values. Turn it off only when your workflow needs the full selected alphabet.
Choose the right generator
Use UUID Generator for UUID v4 identifiers, Number List Generator for ordered labels, and Random Password Generator for password candidates that should be saved securely.
Encode or hash after generation
After creating sample values, use Base64 Encoder/Decoder, URL Encoder/Decoder, or Hash Generator when a mock payload needs another representation.
Quick answer
Random String Generator is a browser-based random string generator for checking copied developer data such as payloads, URLs, encoded values, identifiers, snippets, or logs without sending the input to a server.

What this tool does
The Random String Generator creates one or more configurable strings with length, character set, prefix, and ambiguous-character controls. Use it for browser-local test data and non-secret identifiers, 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
- Choose how many random strings to generate and how long each generated segment should be.
- Select uppercase letters, lowercase letters, numbers, symbols, and whether confusing characters should be removed.
- Add an optional prefix such as id_, test-, or fixture_ when the strings need a recognizable label.
- Generate a fresh batch, copy the output, and use it in fixtures, spreadsheets, docs, QA notes, or mock API examples.
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, stored, fetched, or logged. Use a dedicated password manager for real account passwords.
Practical notes for this tool
Best use case
Use Random String Generator when you need disposable sample identifiers, placeholder coupon codes, QA data, demo labels, or non-production tokens for documentation and testing.
Generate QA fixture labels
Need 6 strings, length 12, letters and numbers
Example-style random strings ready to copy into a staging fixture or documentation draft
Privacy and local processing
Strings are generated in your browser and are not stored by ClearUtils. Generated values disappear unless you copy them, and they should not be treated as managed production secrets.
Limitations to know
- It does not save or rotate generated values.
- It does not check whether a value is already used in your system.
- It is not a password manager or production secret generator.
Practical FAQ
Should I use this for production passwords or real secrets?
No. It is useful for disposable sample strings and test data, but production passwords, API keys, and account secrets should come from your approved password manager or secret-management system.

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.
