About the Sequence Generator
Generate customized sequences of numbers or strings in bulk. Useful for creating order numbers, serial codes, test data, and numbered lists with custom prefixes and suffixes.
How to Use
Set the prefix and suffix, define the start and end numbers, and optionally adjust the step and digit padding. Click Generate to create the sequence. Results can be copied to clipboard.
Output Formats
Sequences can be generated as plain text, comma-separated values, or JSON arrays. Choose the format that best suits your needs.
▶What is digit padding?
Digit padding adds leading zeros to numbers. For example, with 4 digits, the number 5 becomes 0005. This is useful for creating uniform-length codes.
▶Is there a limit on sequence length?
The tool can generate thousands of items. However, very large sequences may affect browser performance.
▶Can I use custom number formats?
Yes, you can set prefix, suffix, step size, and digit padding to create sequences in any format you need.
