List of numbers from 1 to 45

The online number list generator instantly creates sequences from 1 to 45.

The tool is handy for numbering in Excel, generating product SKUs, or preparing question templates. It supports horizontal and vertical layouts, various delimiters, leading zeros, and wrapping.

How to build a list of numbers 1–45

The range 1–45 is set automatically. Follow four steps:

• Layout: “Column” or “Row”.
• Delimiter: comma, period, dash, space, “/”, “|”, or a custom character.
• Preview: the result updates instantly.
• Generate & copy: click “Generate”, then “Copy”.

Additional options

Step (interval): enter an integer to create sequences such as 3 → 3, 6, 9… or 10 → 10, 20, 30….

Leading zeros: adds a zero before shorter numbers to keep equal length: 001, 002… Handy for SKUs and IDs.

Wrapping: choose characters before and after the number to add brackets, quotes, or another style.

Delimiters

You can create the list without a delimiter or pick one of the presets. For a custom symbol, choose “Custom”.

Wrapping

By default, numbers are unwrapped. To add brackets or custom characters, pick “Custom”.

Can’t find the symbol you need? Choose “Custom” and enter your delimiter or wrapper.

Use cases

Educational materials: question or reading lists for classes and tests.
