## Excel formula to power query M code

Hi all, Im trying to convert the following formula in excel to M code :

=CONCATENATE(H2,
MID("ABCDEFGHIJKLMNOPQRSTUVWXYZ012345",(
IFERROR(IF(FIND(MID(H2,1,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,1,0),0)
+IFERROR(IF(FIND(MID(H2,2,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,2,0),0)

+IFERROR(IF(FIND(MID(H2,3,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,4,0),0)
+IFERROR(IF(FIND(MID(H2,4,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,8,0),0)
+IFERROR(IF(FIND(MID(H2,5,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,16,0),0)
+1),1),
MID("ABCDEFGHIJKLMNOPQRSTUVWXYZ012345",(
IFERROR(IF(FIND(MID(H2,6,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,1,0),0)
+IFERROR(IF(FIND(MID(H2,7,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,2,0),0)
+IFERROR(IF(FIND(MID(H2,8,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,4,0),0)
+IFERROR(IF(FIND(MID(H2,9,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,8,0),0)
+IFERROR(IF(FIND(MID(H2,10,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,16,0),0)
+1),1),
MID("ABCDEFGHIJKLMNOPQRSTUVWXYZ012345",(
IFERROR(IF(FIND(MID(H2,11,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,1,0),0)
+IFERROR(IF(FIND(MID(H2,12,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,2,0),0)

+IFERROR(IF(FIND(MID(H2,13,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,4,0),0)
+IFERROR(IF(FIND(MID(H2,14,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,8,0),0)
+IFERROR(IF(FIND(MID(H2,15,1),"ABCDEFGHIJKLMNOPQRSTUVWXYZ")>0,16,0),0)
+1),1))

Assuming, H2 is a 15 digit string of mix of letters and numbers.

Please can you help me out with this.

It looks like you are looking for the letters in your initial string. I put your formula into Excel. Can you exlpain how you get DAY suffix from that starting string (that only has two letters in it)?

Hi @ppm1 Apologies, I made a mistake in  my question. The original 15 digit string is a mix of letters and numbers.

Solution Sage

Can you give an example of an input string with the expected output? The one shown isn't clear.

@ppm1 hi, here is an example of the 15 digit string - 0062o00001CG0Ob

Helper I

hi @ppm1 do you have any solution or anywhere I can start ?

Solution Sage

This is fairly complex but it does match the Excel result (when all the letters are upper case). Add a custom column and put the code below in the pop-up box, replacing TextColumn with the name of your text input column.

``````let
input = Text.Upper([TextColumn]),
letters = {"A".."Z"},
concatvalues = {null, "A".."Z", "0".."5"},
splitinput = List.Split(Text.ToList(input), 5),
lettercheck = List.Transform(splitinput, (x)=> List.Transform(x, (y)=> Number.From(List.Contains(letters, y) ))),
multipliers = {1,2,4,8,16},
listsums = List.Transform(lettercheck, (a)=> List.Sum(List.Transform({0..4}, (b)=> a{b}*multipliers{b}))),
listvalues = List.Transform(listsums, each concatvalues{_+1}),
result = input & Text.Combine(listvalues, "")
in
result``````

Hi @ppm I modified your code to give me that lower case O in the middle, and it goes like this:
let
input = [Opportunity ID],
letters = {"A".."Z"},
concatvalues = {null, "A".."Z", "0".."5"},
splitinput = List.Split(Text.ToList(Text.Upper(input)), 5),
lettercheck = List.Transform(splitinput, (x)=> List.Transform(x, (y)=> Number.From(List.Contains(letters, y)))),
multipliers = {1, 2, 4, 8, 16},
listsums = List.Transform(lettercheck, (a)=> List.Sum(List.Transform({0..4}, (b)=> a{b} * multipliers{b}))),
listvalues = List.Transform(listsums, each concatvalues{_+1}),
result = input & Text.Combine(listvalues, "")
in
result

Thanks for the help and hope I can come back to you with feedback and more help

@ambi95 Have you been able to try this out?

Can I ask, was there any specific reason you used Text.Upper for the input?

Helper I

Hi @ppm1 I modified your code to give me that lower case O in the middle, and it goes like this:

``````let
input = [columnname],
letters = {"A".."Z"},
concatvalues = {null, "A".."Z", "0".."5"},
splitinput = List.Split(Text.ToList(Text.Upper(input)), 5),
lettercheck = List.Transform(splitinput, (x)=> List.Transform(x, (y)=> Number.From(List.Contains(letters, y)))),
multipliers = {1, 2, 4, 8, 16},
listsums = List.Transform(lettercheck, (a)=> List.Sum(List.Transform({0..4}, (b)=> a{b} * multipliers{b}))),
listvalues = List.Transform(listsums, each concatvalues{_+1}),
result = input & Text.Combine(listvalues, "")
in
result``````

Thanks for the help and hope I can come back to you with feedback and more help

Solution Sage

I'm sure this can be done in the Power Query editor with Text.Split and list functions, but can you explain your logic? Also, your example value has only 13 characters.

@ppm thanks for the suggestion, could you tell me how ad where to start ?

basically the logic is that we want to convert a 15 digit code to another 18 digit code - using that formula above
