My ABRCB Excel Sheet
I use the excel sheet below to record, calculate, and keep track of horse records. I also can generate DODs in the sheet. I am currently working on a written tutorial but if you have knowledge of excel formulas, you might be able to figure out what's going on. You are more than welcome to download this sheet and play around with it and if you have any specific questions, feel free to reach out and I can try to help.
Requirements: This sheet will break if you try to open it using the browser version of Excel or Google Sheets. You must have a desktop version of Excel to open this sheet without it falling apart and while not required, I recommend you have a recent version of Excel. I have successfully opened this file using Excel 2003, but the program didn't handle it very well and was very prone to breaking.
