How to create a list of numbers from 1 to 55

The range 1–55 is set automatically. Complete four steps:

Format: “Column” or “Row.”
Delimiter: comma, period, dash, space, “/”, “|” or your own symbol.
Preview: see the result immediately in the preview panel.
Generate & Copy: click “Generate,” then “Copy.”

Additional features

Step (interval): enter any integer—for example, 3 → 3, 6, 9… or 10 → 10, 20, 30….

1, 4, 7, 10, 13, …

Leading zeros: add zeros before shorter numbers: 001, 002… Ideal for SKUs and IDs.

001, 002, 003, … 010

Enclosing: choose characters before and after numbers—parentheses, quotes, or custom symbols.

(1), [1], {1}, <1>

Delimiters

You may use no delimiter or select a standard one. For a custom symbol, choose “Custom.”

Type	Symbol	Example
Comma	,	1,2,3,4,5
Comma + space	,	1, 2, 3, 4, 5
Space		1 2 3 4 5
Dash	–	1-2-3-4-5
Period	.	1.2.3.4.5
Period + space	.	1. 2. 3. 4. 5
Vertical bar	\|	1\|2\|3\|4\|5
Slash	/	1/2/3/4/5

Enclosing

By default there is no enclosing. To add brackets or custom symbols, select “Custom.”

Type	Before	After	Example
Round brackets	(	)	(1)
Square brackets	[	]	[1]
Curly braces	{	}	{1}
Angle brackets	<	>	<1>

For custom delimiters or enclosing symbols, choose “Custom” and enter your characters.
