"Random string" is a utility for creating custom random strings. Ideal for developers, testers, and anyone needing unique identifiers, placeholders, or secure tokens. Each string is generated from your specified character set, with optional prefixes/suffixes and length controls.

Use cases

Common use cases for random strings:

1. Unique IDs: Generate unique identifiers for databases, APIs, or user sessions.
2. Placeholder Data: Create realistic test data for UI mockups or database seeding.
3. Security Tokens: Produce one-time tokens for authentication or password resets.

Tool settings

Configure your random strings with these settings:

1. "Length":Length of each string (e.g., 10 characters).
2. "How many":Number of strings to generate (e.g., 5).
3. "Suffix/Prefix":Optional text to append/prepend to each string (e.g., 'user_' prefix).
4. "Characters":Character set to use (e.g., 'abc123' or 'A-Z0-9').
5. "Exclude spaces":Toggle to ignore spaces in the character set.

How to use

Step-by-step usage guide:

1. Set the number of strings and their length.
2. Define a character set or use the default (A-Z, a-z, 0-9).

4. Toggle 'excludeSpaces' if needed.
