Extracting text IF these conditions are met (Power Query)

[campelliann]

Hi,

I need my coleagues to fill a Project ID field, the problem is that there are many digits, and some people forget to put some zeros. E.g. P2019000000555 some people put P20190555, for example. (I need to do a kind of "sumif", of the work done in each ID.

To work around this, I am thinking on a simplified ID field, witch extracts the 5 first Characters, and last 4. This should solve the majority of my problems (although i am open to other ideas). Although I want to do this extraction (first 5, last 4) only when the ID starts with P2018, P2019, P2020 etc... More examples.

ID: P2019000000723 - transform to P20190723

ID: P20200000005233- transform to P20205233

ID: PAC1241 - stays the same

ID: MP2323 - stays the same.

Many thanks!

Hi, @campelliann 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may add a custom column with following codes in 'Query Editor'.

let 
len = Text.Length([ID]),id = [ID]
in
if len>=9 then
Text.Middle(id,0,5)& Text.Middle(id,len-4,len-1)
else id

Result:

Hi Allan,

This almost works, the problem is that I have some text fields which lenght is >= 9, and I want them to stay the same.

Ist it possible, instead of using the condition len>=9,  if text contains "P20??".

Many thanks

if Text.Contains("ID","P20") and len>=9 then

    #"Added Custom" = Table.AddColumn(Source, "Custom", each if Text.Length([Column1])>9 then Text.Start([Column1],5) & Text.End([Column1],4) else [Column1])
in
    #"Added Custom"

In the query editor, just highlight that column and click on Replace Values in the ribbon.  Enter "000000" and "null" in the two fields in the popup (w/o the quotes), and hit ok.

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
