An auto custom column

[inawab]

Hi everyone,

I am not sure if this can be done, I have below column

I Split Column by Delimiter "/" 

there will be up to 21 new column, now I need to join every 2 column with the below condition 

if [Routing.2] = [Routing.3] then [Routing.3] &"-"&[Routing.4] else

if [Routing.2] <> null and [Routing.3] <> null then [Routing.2]&"-"&[Routing.3] else null

and I must repeat this up to twenty-one time each time with the next columns, so the next one will be:

if [Routing.3] = [Routing.4] then [Routing.4] &"-"&[Routing.5] else

if [Routing.3] <> null and [Routing.4] <> null then [Routing.3]&"-"&[Routing.4] else null

there will be times when I will have more than twenty-one columns after the Splitting, therefore I need to rebate above formula more than twenty-one time.

My question can we auto this process so it can be adjusted to any changes happen in the future?

Hi @inawab ,

Can you supply your original example table in a copyable format please?

Best to copy that column in Power Query, paste it into Home tab > Enter Data, then copy and paste the Advanced Editor code from that into a code window ( </> button ) here.

Please also provide an example of what your expected output looks like for a few rows of the original table.

this up to 4 repeats
