# A Free Excel Add-in Function: Convert Shorthand Notation

Because A Smart Student Asked An Insightful Question

In business reports, large numbers are often reported in numeric shorthand notation like \$2.5B or USD25M. While we can use the format cells dialog to create a custom number format, the majority of data we may import from other data sources will include a letter, which converts numbers to text when used in Excel.

In the process of teaching my classes, a smart student asked: Why isn’t there an easy way for Excel to allow me to convert \$2.5B to a number like 2,500,000,000 that I can use in my formulas. This insightful question led me to develop a new Excel function I call Convert Shorthand Notation, or CSN. This free custom Excel feature adds functionality to your Excel workbooks to simplify your workflow.
I hope you find this feature useful. Please let me know if you feel it can be improved with additional functionality or features.

## To Install The CSN Add-in:

1. Excel Add-in files are typically stored in the following directory:
However, you can save this file anywhere on your computer or network, but in a location that should not change and one where you may remember where it is located.
2. In Excel, choose the File tab > Options Command.
3. In the Excel Options dialog, along the left, select the Add-Ins category.
4. To the right, locate and select the Go… button.
5. Click the Browse… button.
6. Browse to the location where you saved the Add-In.
7. Click the OK button 2-3 times to close all dialogs.

## How To Use the Excel CSN Function:

Note that this Add-In will not modify the ribbon. To use the feature in a cell, type =CSN( and then reference a cell with a value (or you can also type a value directly) to covert from shorthand text to a longer numeric value. The CSN function can also be nested inside other functions like VLOOKUP, XLOOKUP or MATCH for the Lookup_Value, in an IF or IFS function as part of a logical test condition, or in a SUMIFS function as part of a criteria.

Note: If you share your workbook with other users who have not installed the Add-In, they can see the result of your formula, but if they change values and recalculate the workbook those formulas will fail without the Add-in. The Add-In feature is globally available to every workbook on your computer but does not travel with the workbook if you email the file.
