Force Convertion of String to Number using Dax

NPbon — Tue, 31 Oct 2023 14:21:21 GMT

Hello everyone,

I have a column that was created with DAX (hence cannot use power query) as a Text that needs to be converted to Number.

However, sometimes on this column there are non-numerical, non-roman characters as the source is taken from multiple languages around the world.

When using CONVERT function, if only in one of the rows there is a special character, all rows are changed to #Error.

I want to know if there is a function that forces the convertion (omitting or deleting the special character) or at least that changes to #Error only the row with the problem, and not the entire column.

Many thanks,

Hi NPbon ,

Plese try to identify the column firstly, then convert the data type, please try to create a column like below dax formula:

Column = VAR cur_val = [Column Name] VAR _a = SWITCH ( TRUE (), ISNUMBER ( cur_val ), CONVERT ( cur_val, INTEGER ), ISNONTEXT ( cur_val ), CONVERT ( cur_val, INTEGER ), "Not number" ) RETURN _a

Hello,
The solution provided Did not work for the intended purpose at all.

When using it I got an error: "Expressions that yield variant data-type cannot be used to define calculated columns".

An Example of my problem, and how I would like the solution (using 0.04 as error code)
14.45 --> 14.45
14# --> 0.04
103 --> 103
$18 --> 0.04

when trying to use 0.04 instead of "Not number", all rows became 0.04

Any other idea with this?
