And one of the handy tools for code breaking is to recognize primes quickly, so Contoso would love to have an ISPRIME function for the millions of detectives who already use Excel. wants to release a solution that helps sleuths analyze data in Excel to decode messages. See Figure 2 for an example: The Contoso Cryptographers Corp.

So if you want to provide a powerful capability that Excel doesn’t already have, consider building an Excel function for that purpose. People at work and in school learn Excel functions to use in formulas, and they interact with them naturally for their day-to-day calculation needs. And then, as soon as you make a change, Calc updates the dependent values based on those formulas.įigure 1 Calc Lets You Create Relationships Between CellsĮxcel provides tons of helpful functions to use in your formulas, from the essential AVERAGE function ( bit.ly/1Tjynwl), to string-analysis functions like SEARCH for finding substrings ( bit.ly/2jhcEuV), to more complex calculations like the T.TEST statistical function ( bit.ly/2ipowKE). Calc is what lets you create relationships between cells: You express complex models by writing simple formulas to describe the dependency trees between values (see Figure 1). And underneath all the fancy features, behind the slick charts and formatting, the real value is calculation, called “Calc” internally. Take a second to think about Excel as a whole-it’s a flexible, powerful, ubiquitous tool for analyzing data, from my handy little to-do list spreadsheet, all the way to massive 100MB financial-model workbooks at the world’s top banks.
