How to use Expressions (Add)

[AakashJaiswal]

Hi @RezaDorrani,

Firstly, thank you for sharing the expressions #01 series on youtube. It helped me a lot. to understand expressions in Power Automate.

I have some queries.

1. I am using expressions to calculate values in approx 54 sharepoint columns (total 120) which consist of many arithmetic + logical functions. These calculations will be done for approx 2000 rows every time. The resultant schema is passed to PowerApps for analysis. Do you think I am overloading PowerAutomate?
2. How can I count 12 columns only when the values inside them are not null? Similar to COUNTA in excel.
3. How can I add more than 2 parameters using Add function? I need to calculate sum of more than 12 columns.

Can you please help?

Others can help too if they know the solution.

Best,

Aakash

Hi @AakashJaiswal,

1. If only has 54 SharePoint calculate columns, it doesn't overload the limits of expression, the characters limitation is 131,072 characters. If you are familiar with calculate column in SharePoint, you could consider using it which will be easier achieved than expression.

Examples of common formulas in lists - SharePoint (microsoft.com)

2. You could use expression empty() to check if each column is true. Then use if() function to switch output. For example:

if(empty(variable('columnA')),0,variable('columnA'))

3. The add() function only accepts two parameters, add(<summand_1>, <summand_2>).  So if 8 columns add, the expression will be as below:

add(add(add(column1,column2),add(column3,column4)),add(add(column5,column6),add(column7,column8)))
