Excel Addin: Sheet-Scoped Name Generator

[ add-ins excel vba ]


I’ve been crafting Excel formulas for fifteen years now, and recently I’ve been seeing the advantages of using the built-in ‘defined names’ functionality. For example, if I have a worksheet that contains a number of physical constants that I’m going to be referring to on a regular basis, it’s a huge time- and brain-saver to define a name for each cell. Case in point, this (now outdated!) periodic table I put together a few years back:

Each of the molecular weight values shown here is in a cell with an assigned name of the format w_Xx, where Xx is the atomic symbol of the element of interest. So, to calculate the formula weight of calcium sulfate \((\mathrm{CaSO_4})\), all I have to do is:


Names can be defined on single cells as well as multi-cell ranges, though most of the time I’ve found naming single cells to be most valuable. Names can be created singly via the Name Manager, accessed by pressing Ctrl+F3 or via Formulas > Defined Names > Name Manager in the Ribbon:

A key thing to note: when adding new names via the Name Manager, it’s possible to choose whether the defined name is created at the scope of the entire workbook, or of a specific worksheet:

Adding a new name

For global constants like atomic weights, the workbook-level scope makes sense. However, much of the time I’m working with multiple ~identical datasets on different tabs, each of which benefits from its own independent set of named cells. Here, the worksheet-scoped names make far more sense.

The Problem

Excel comes with a built-in tool for quickly defining a large number of names at the workbook scope based upon the values in neighboring cells, accessed either via Ctrl+Shift+F3 or by Formulas > Defined Names > Create from Selection in the Ribbon. Take my periodic table example; say I highlight one of the elements and its atomic weight like this:

Nickel cells highlighted

Activating Create from Selection shows the following dialog:

Excel has automatically selected Top row, which is indeed what I would want to use here: clicking OK would create a workbook-scoped name of Ni assigned to the cell containing 58.693. (Note that I didn’t actually use Create from Selection to make this periodic table, since my names have that w_Xx syntax, but this gets the idea across.)

So, this is handy – what’s the problem? Well, the problem is that, to the best of my knowledge, there’s no way to do this sort of bulk, automatic name definition for worksheet-scoped names.

The Solution

… was to write my own add-in, obviously, which you can find at bskinn/excel-sheetscopename. To install:

  1. Download the most recent SheetScopedName.xlam from the Releases page.

  2. Follow the instructions here to install and activate the add-in (looking for Sheet-Scoped Name Generator instead of CSV Exporter in the add-ins list).

To create worksheet-scoped names, start by highlighting a block of cells that you want to be named based on the contents of the cells to the left, e.g.:

Then, press Ctrl+Shift+N and the names will be applied to each cell:

The Issues page has a few known bugs to be fixed, and some potential enhancements to be implemented.
