For whatever reason, sometimes we just need a list of alphanumeric letters and numbers like this “0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ” to run down a column or across a row, or just all packed into one string of text in a cell in our Google Sheet.
I most commonly use an alphanumeric list to index data or use an alphanumeric string in the random assignment of a value.
In this tutorial, we will cover 4 ways to achieve this. Some approaches have different benefits than others. While two of the approaches even use the new Google Sheets LAMDA function.
If you just want to dive in, copy the formula, and get back into your own project, click on the link to the main numbered headers in the table of contents below. You can copy the formula into your project using the copy symbol in the dropdown menu of the formula bar and selecting the formula you want.
Each formula type can be:
- Transposed to run across a row.
- Join into a string in a cell.
- Set to lowercase.
- Extended to include a lowercase option.
The How it Works sections are not mandatory reading but might be helpful if you plan to extend the formula or are simply curious.
Oh, and number 1 is my favorite.
