SharePoint Calculated Columns and Validation Formulas: Everything you need to know about SharePoint formulas for SharePoint 2010 to 2019 and SharePoint Online / Office 365

This book is for the SharePoint “power user” who needs a better understanding of how SharePoint formulas work, where they don’t work, and how they are created. While at first glance SharePoint formulas appear to be simple calculations, they are both quite powerful and have weird limitations. In this book we will explore the basics of creating Calculated Columns and Validation formulas with some boring details, and over one hundred examples. We also explore workarounds for many of the limitations by using SharePoint Designer workflows and a few tricks!Where are formulas used in SharePoint?•Calculated column formulas derive data from other columns in the same list item. These can be simple calculations and text manipulations, or complex Excel-style formulas.•Column validation formulas are used to create custom validations for user entered data. These can be used to make sure that "quantities" are not negative and vacation requests are for dates in the future.•Column default formulas, while very limited, can auto-fill columns with a date 30 days in the future or a message based on the month or day of the week the item was added.•List / Library validation formulas are used to check the values from multiple columns to verify the relationship between two or more columns. Examples include making sure a task start date is before the task end date, or to make sure an entry has a "price per pound" or a "price each", but not both.Who is this book for?Anyone who works with creating and customizing lists and libraries.
