pull one character out of text string

[gouldc2]

I have a list of serial codes that I want to pull individual characters out of that relate to a date made. For instance I want the third digit (7) out of CH78KG092 to put into a new column because that corresponds to the year made (2017). In excel I use a mid function. How to do in power BI? Thanks.

DAX has MID( ) as well

M Code also has similar Text.Middle( )

There are a couple different functions that you can use, one being Text.Middle.

Below is how that function works, but you can always use the following link to play around with other functions:

https://msdn.microsoft.com/en-us/query-bi/m/power-query-m-function-reference

Text.Middle(text as nullable text, start as number, optional count as nullable number) as nullable text

About

Returns count characters, or through the end of text; at the offset start.

Example 1

Find the substring from the text "Hello World" starting at index 6 spanning 5 characters.

Text.Middle("Hello World", 6, 5)  

Equals: "World"
