One of the most popular posts on this blog is how to become excel conditional formatting rock star. Quite a few commenters there asked me if there is a way to get more than 3 (or 4) conditional formats in excel 2003. Like what you see below:
You can get more than three conditional formats in excel using VBA / macros. Last week I had sometime to put together a simple VBA script using which you can get more than 3 conditional formats in Microsoft excel. Just follow the below 3 steps.
- Download the VBA Macro for getting more than 3 conditional formats
Just copy the VBA Macro cFormat() to your workbook or place it in wherever you keep all your macros. - In your workbook, define 3 named ranges.
data2use: This range contains the cells to be formatted.
conditions2use: This range is identical in shape and size to data2use and contains conditions for the data range start from 1 to n (n being the maximum number of conditional formats your would like to have)
formats2use: This range contains “n” cells each formatted in a way you would like to format the cells in data2use range.See this illustration to understand how these 3 ranges are used to create more than 3 conditional formats:
- Finally hit Alt+F8 (or menu > tools > macro > macros) and run the cFormat macro. The conditional formatting macro you have just downloaded will format the “data2use” range by scanning “conditions2use” range and using the formats in “formats2use” range. If you are curious to see how the VBA script looked like, see the cFormat macro code
- Make sure you have downloaded the workbook with code for getting more than 3 conditional formats in excel
What would you use this trick for? A giant heat map, project plan … ?

Do you have links to any sites that can provide free, large, test data sets. Both large in diversity and large in total number of rows.
Good question Ron. I suggest checking out kaggle.com, data.world or create your own with randbetween(). You can also get a complex business data-set from Microsoft Power BI website. It is contoso retail data.
Hi Chandoo,
I work with large data sets all the time (80-200MB files with 100Ks of rows and 20-40 columns) and I've taken a few steps to reduce the size (20-60MB) so they can better shared and work more quickly. These steps include: creating custom calculations in the pivot instead of having additional data columns, deleting the data tab and saving as an xlsb. I've even tried indexmatch instead of vlookup--although I'm not sure that saved much. Are there any other tricks to further reduce the file size? thanks, Steve
Hi Steve,
Good tips on how to reduce the file size and / or process time. Another thing I would definitely try is to use Data Model to load the data rather than keep it in the file. You would be,
1. connect to source data file thru Power Query
2. filter away any columns / rows that are not needed
3. load the data to model
4. make pivots from it
This would reduce the file size while providing all the answers you need.
Give it a try. See this video for some help - https://www.youtube.com/watch?v=5u7bpysO3FQ
Normally when Excel processes data it utilizes all four cores on a processor. Is it true that Excel reduces to only using two cores When calculating tables? Same issue if there were two cores present, it would reduce to one in a table?
I ask because, I have personally noticed when i use tables the data is much slower than if I would have filtered it. I like tables for obvious reasons when working with datasets. Is this true.
John:
I don't know if it is true that Excel Table processing only uses 2 threads/cores, but it is entirely possible. The program has to be enabled to handle multiple parallel threads. Excel Lists/Tables were added long ago, at a time when 2 processes was a reasonable upper limit. And, it could be that there simply is no way to program table processing to use more than 2 threads at a time...
When I've got a large data set, I will set my Excel priority to High thru Task Manager to allow it to use more available processing. Never use RealTime priority or you're completely locked up until Excel finishes.
That is a good tip Jen...
