Another aspect where Copilot shines is its ability to explain formulas. This feature is particularly useful for those who wish to learn and understand what each formula does. By selecting 'Explain Formula,' Copilot breaks down the components of the formula in an easy-to-understand manner. This not only helped me verify that the suggested formula was correct but also served as a learning tool.

Example of Copilot adding formula columns - Numbers

I have a two fields with numbers. FY23 and FY24. In the Copilot prompt box I typed

1. calculate the percentage difference from FY23 to FY24 in a new column
2. Copilot came back with the correct formula =([@FY24] - [@FY23]) / [@FY23] and I can preview the results.
3. I clicked Insert Column, and the Percentage Difference shows in column J. 

Example of Copilot adding formula columns - Dates

I have a Invoice Date field (column G),. I want the month in a column and I want the month as a three letter abbreviation. January is Jan, February is Feb. In the Copilot prompt box I typed

1. Add a column showing the Invoice Date as a three letter month
2. Copilot came back with the correct formula =TEXT([@[Invoice Date]],"mmm") and I can preview the results.
3. I clicked Insert Column, and the Month shows in column K. 

Example of Copilot adding formula columns - Text

I have First name and Last Name is two separate columns. I want the names combined.

1. In the prompt box I type Add a column combining the First Name and the Last Name. Name the column Full Name.
2. Copilot correctly uses Concatentate fucntion to combine the names. 

Notice is this example, I added to the prompt what I wanted the column named.
