Optimizing SharePoint List Calculated Column for Numeric Values


When it comes to SharePoint Calculated Column Optimization, working with SharePoint frequently presents obstacles, particularly regarding the formatting of numbers in calculated columns. This guide aims to provide a solution to the problem where numbers don’t format correctly in SharePoint calculated columns, especially when integrated with Power Apps. If you’ve noticed your numbers appearing with trailing figures or not displaying as intended, read on.

Understanding SharePoint Calculated Column Optimization Challenges

It’s a recognized issue within the SharePoint environment that numeric calculated columns sometimes fail to cooperate. Specifically, when working with Power Apps, it might not accurately recognize the data type for these columns, leading to formatting challenges. Fortunately, there’s a way to counteract this.

Steps for Effective SharePoint Column Optimization in Power Apps

Let’s illustrate the issue with a practical example:


Consider a SharePoint list containing property details. Among other columns, there’s an acquisition price column and another calculated column that transposes this price into US dollars by multiplying it by an exchange rate. When defining this calculated column, it’s specified to display results up to 2 decimal places.

Sample Power App Creation

When we initiate an auto-generated app and include our calculated field in a detail form, the issue becomes evident. Instead of displaying a numeric icon, an ‘abc’ icon emerges next to our calculated ‘AquisitionPriceUSD’ field. Furthermore, when the app is played and we navigate to the record details screen, the value of our calculated column astonishingly displays up to 9 decimal places!


To rectify this, we need to transform the string value back into a numeric form. This is accomplished using the Value function. Subsequently, to limit the number to a defined set of decimal places (like 2), the round function can be utilized as demonstrated below:


For detailed formatting, like including thousand separators, the value is first turned into a number and then reverted to a string format. This is executed by invoking the Text function and providing a custom format string:
