Replace only some values in a column

[Lagoona23]

I'm just starting out with Power BI so any help will be most appreciated.

Is it possible to select some cells in a column and replace text only in those?

For example I have the number 12 in a number of cells in column A but I only want to change 12 to 2 for some of them based on the value of a different column. Example change 12 to 2 where month is February but not where month is March.

It doesn't seem possible to just highlight the rows I want to change and then select the replace feature as I would do in Excel.

Thank you.

@Lagoona23 , In power query M you have If else

example

New Margin = ((if [Item.Brand] = "Brand 1" then 5 else
if [Item.Brand] = "Brand 2" then 5.5 else
if [Item.Brand] = "Brand 3" then 6.0 else
if [Item.Brand] = "Brand 4" then 6.5 else
7.0 )*([Qty]*[Price]) *((100-[Discount Percent])/100))/100

And text function https://docs.microsoft.com/en-us/powerquery-m/text-functions

with help of that you can do that

Hi @Lagoona23 

The easiest way would be to add an extra Conditional Column in Power Query/Transform data specifying your conditions.

Happy to assist further if you can provide a data sample.

Thank you @Mariusz this worked for me, but have since noticed that you can only include 1 conditional - eg: you can't say If column A = 5 AND Column B = 5 so for some other transformations I'm looking at other things. Having an issue with concatenating 2 columns now but will post a separate question I think.

By the way the dataset I'm trying to transform is Avi Singh's Ultimate Calendar table - I'm changing it to suit my companies fiscal year.

Ah yes thank you I hadn't found that, it looks like it could work I will try it - many thanks.
