Classic tool
Random String Generator
Generate random strings with letters, numbers, symbols, prefixes, suffixes, and custom exclusions.
Use this random string generator to create test codes, internal identifiers, temporary names, coupon values, and custom sequences in seconds. You control the length, the number of results, and which character groups appear in each string.
The tool can mix lowercase letters, uppercase letters, numbers, symbols, and extra characters that you provide yourself. You can also remove specific characters, filter out ambiguous symbols, and add prefixes, suffixes, or separators so the final output is ready to paste.
That makes it useful for development, QA, automations, spreadsheets, sample data, and any workflow where you need several consistent strings without building them manually.
Use clear inputs to get a more useful result.
How to use the generator
Set the length of each string, choose how many results you want, and enable the character groups that fit your use case. Add a prefix, suffix, or custom separator if you want the output formatted for another tool or system.
When this tool helps
- Creating temporary codes for tests and staging.
- Building identifiers that follow an internal pattern.
- Preparing quick batches for coupons, placeholders, and sample records.
Practical tip
If readability matters, keep ambiguous characters excluded so values like 0, O, l, and I do not get mixed up.
