IF conditions for filtering in Power Query

[PCarson00]

I have a set of data I want to filter in one column but not sure how to go about this. Here is my attempt at the explanation

IF text begins with "L01" or "L04"

then

remove first 3 characters

Else

Remove first character only

Is this possible to write in power query?

pls try this

if Text.Start([DATA],3) ="L01" or Text.Start([DATA],3) ="L04" then Text.RemoveRange([DATA],0,3) else Text.RemoveRange([DATA],0,1)

or========
if Text.StartsWith([DATA],"L01") or Text.StartsWith([DATA],"L04") then Text.RemoveRange([DATA],0,3) else Text.RemoveRange([DATA],0,1)

Hi @PCarson00 ,

How about this:

I created a new column with your requirement and the following code in M:
if Text.StartsWith([Column], "L01") or Text.StartsWith([Column], "L04") then Text.RemoveRange([Column], 0, 3 ) else Text.RemoveRange([Column], 0, 1 )

Let me know if this solves your quest 🙂

Thanks Tom. On my end its not working - getting an error 'then' expected. I notice the or command is not blue?

Hi @PCarson00 ,

This is probably because there was some other stuff ("Table.AddColumn..., each") in the custom column formula box. My screenshot was probably misleading 🙂 

Here how it's supposed to look like:

Happy you found a solution anyway! 🙂
