A QUICK GUIDE
How it works
- Set the length of the random part and the number of codes.
- Choose character types or enter your own printable ASCII characters.
- Add a fixed prefix or suffix if you need one, then generate.
GOOD TO KNOW
Characters and uniqueness
- The length applies only to the random part, not the prefix or suffix.
- Unique codes are checked against the available combinations before generation.
Which download format should I use?
TXT and JSON preserve the generated values. CSV adds an apostrophe before values that a spreadsheet might treat as formulas; choose TXT or JSON when you need the original value.
