Detailed List of Worksheet Functions

Overview of formulas supported in ProjectTeam Worksheets, how they differ from Excel, and how they help automate calculations within construction project management forms.

Overview

ProjectTeam Worksheets offer a powerful way to calculate values, analyze data, and automate logic directly inside your forms. While the experience will feel familiar to anyone who has used Microsoft Excel, the formula engine in ProjectTeam is purpose-built for construction project management workflows. This means many common Excel-style formulas are supported, but not all Excel functions behave the same way, and some formulas available in ProjectTeam are unique to the platform.

ProjectTeam formulas are designed to:

  • Automate complex calculations inside each worksheet
  • Reference other data and rows within the worksheet for real-time updates
  • Improve data accuracy and reduce manual input

Because the worksheet engine is optimized for form-based use, certain Excel functions such as macros, complex array formulas, and external references are not supported. The following help page lists all formulas currently supported in ProjectTeam Worksheets, along with usage notes and examples.

Boolean Operators

You can compare two values via using logical expressions that in any given case will only return either TRUE or FALSE.
