Leave only the integers in a column

Hey everyone,

I want to remove every character in the cells of a column and leave only the integer values.

For example if the datatable is like this:

I want to do this to the “Equals” Column
so output DT should be:


And I dont want to use for each row because the excel I have has around 10k rows.

Any suggestions?

Hi @jntrk

Try this way

  1. Use read range to read the datatable and store in dt1

  2. use assign activity like this

dt2 = dt1.AsEnumerable().Where(Function(row) System.Text.RegularExpressions.Regex.Replace(row(“Equals”).ToString, “[^\w\d]+”, “”)).CopyToDataTable

Try this

It gives the error Option Strict on Disallows implicit Conversion from “String” to Boolean

Why this error message is given? Do you have any idea?

Check this link:

I couldnt figure out how this will help the problem I face? I read it but I couldnt find a solution for this problem

The conversion issue comes from the linq Statement. the Lambda Expression within the where Statement requires a Return of boolean which is Used for the Filter Evaluation.

The given predicate Returns a String and this is reason why IT comes to this validation Message.

Updating a column value with the Help of linq within an assign Activity requires some exploits. For Setting up such a Statement IT would be helpfully for ja that you will Share the complete datatable column structure with US.



There are 8 columns in the datatable. the column I want to alter is named “Percent” it consists of values such between 0%-300% and the values come from a formula written inside the column cells but when I read range it takes the values not the formula, besides I dont need it to read the formula just the values inside the cells. Is there anyother info you need?

Any news? I still couldnt make it work.

I am attaching a sample excel.sample.xlsx (9.3 KB)

Hi @jntrk

Sorry for delayed response

Try this in invoke code

dt1.AsEnumerable().ToList().ForEach (Sub(row) row(“Equals”)=System.Text.RegularExpression.Regex.Replace(row (“Equals”).ToString,"[^0-9]+").Value)

Hope it helps you
