Convert mixed column Hexadecimal to Decimal in DAX or Power Query

[jayblog]

I have a column that has mixed hexadecimal MEIDs (mobile equipment identifier - 14 characters) and decimal MEIDs (18 characters).  I'd like to convert the hexadecimal MEIDs in the column to decimal and leave the decimal ones alone.

I used this formula in Excel to accomplish the task, but I can't get my DAX or Power Query attempts to work.  Any help would be appreciated.

=IF(LEN(A2)=14,CONCATENATE(TEXT(HEX2DEC(LEFT(A2,8)),"0000000000"),TEXT(HEX2DEC(RIGHT(A2,6)),"00000000")),(A2))

*Red text denotes the Excel cells.

@jayblog,

You may add a custom column as follows.

if Text.Length([Column1]) = 14 
then Text.PadStart(Text.From(Expression.Evaluate("0x" & Text.Start([Column1], 8))), 10, "0") 
& Text.PadStart(Text.From(Expression.Evaluate("0x" & Text.End([Column1], 6))), 8, "0") 
else [Column1]
