Overview

If you’ve used Excel for more than a couple minutes, you’ve probably used formula references and know a couple of the symbols for them. Knowing all of them though is crucial for building quality and optimized formulas and workbooks.

In this article, we’ll walk through the nine of the symbols you can use with formula cell references.  This will help you understand formulas and write them the correct way.  Make sure to grab a copy of the example workbook that accompanies this article using the box below!  And if you want to learn the top 52 Excel functions worth using, check out this comprehensive template.

Why use formulas with cell references

Cell references are the backbone of Excel.  Without them, Excel isn’t much better than a big calculator.  But with them, you can build completely dynamic files that can go well beyond financial reporting. It’s borderline programming!

I make it a goal to minimize hard-coded values as much as possible and maximize formulas.  And not just for the cell values, also in conditional formatting.  I also use a small arsenal of macros to reuse formulas and formats and check for cells that are hidden or don’t contain formulas.

And now that we have dynamic array functions and dynamic references (see the last two symbols below), they’re even more dynamic!  These are relatively new concepts, so if you aren’t familiar with them, give them a try today!

The formula symbols

1. Dollar sign ($)
Dollar signs drive the reference type (relative, absolute, or combination) and guide how Excel applies copy/paste of formulas.  The screenshot below show how best to use them in formulas to make them scalable.
2. Colon (:)
Colons are used to define/separate the top-left and bottom-right cells in a contiguous range or a block of cells.
3. Comma (,)
Commas are used to separate multiple individual cell references or ranges of cells (they can be combined with colons). Note that commas also separate arguments within a formula function, which may or may not be cell references.
4. Exclamation point (!)
An exclamation point is used to identify a sheet name in front of a reference. Note that if the sheet name contains  any spaces, single quotes are also needed around the sheet name and prior to the exclamation point.
5. Single quotes ('')
Single quotes (or apostrophes) are used to identify a sheet name (with 1+ spaces) and/or file names/paths in front of a reference.
6. Brackets ([])
These are used to identify a file name in front of a sheet name/reference. Note that if the reference is to a named range, the file name would not have brackets around it.
7. Curly brackets ({})
While not technically used with cell references per se, it’s useful to know what they do. Curly brackets are used to enter an array of values to be processed with dynamic array functions, or define the formula as an array-based formula.
8. Hashtag (#)
A newer symbol used with formula references, the hashtag is used to indicate referencing an entire array of values.
9. Period (.)
The newest of the formula reference symbols, this one is a game-changer!  The period (also known as the dot operator) is used to trim the empty values from a cell range.  It must come before and/or after the colon in a cell range reference.  It is a shortcut for using the TRIMRANGE function.  This makes your range dynamic where it will automatically shrink or expand to accommodate the non-blank cells in your referenced range.

Working with named ranges

So far, we’ve covered all the symbols you need to know when working with cell references – within the same sheet, another sheet, or even another file.  Another incredibly useful cell reference concept is named ranges.  If you’re going to use Excel like a pro, named ranges are a must-know Excel feature.  To learn about them in-depth, check out this dedicated article on named ranges.

Key reasons why you should consider using named ranges include:

  1. Simplifying formulas/references and making them easier to read/understand
  2. Giving you a central reference – like a tax rate input – that you can update in one place and reflect throughout
  3. Giving you another way to make dynamic references that can expand or contract automatically as the data changes
  4. They work well with other valuable Excel features, such as data validation and conditional formatting
  5. They are crucial for working with macros as traditional cell references don’t shift when you insert/delete rows or columns, but named ranges will reflect those changes

Summary

Knowing how formula references work is a crucial and fundamental skill for every Excel user to master.  And that doesn’t just mean the basic stuff like colons and commas, it also means referencing other sheets and files, and the newest symbols (hashtags and periods) that make your files even more dynamic.  There have been a lot of great updates to Excel in the last few years, and these are two of them.  Don’t get left behind!
