populating empty slots with data

Hi there,

I need some kind of way to populate column "name" with names by some algorithm going through names, in indexed order and if name field empty previous name from previous fields from the same column should be used, until it reaches new name and starts populate fields with new name. I've been trying to create funtion for that but it's just too complicated for me, need help.

Added examples of data what I've got (left picture), and what I want to get (right picture) Examples created in Excel but the real data in power bi and I need a solution for it

    Hi alex-JF,

     

    Bring your table into Power Query

    Make sure the [Name] column has nulls not empty text strings. If it does contain empty text strings go to the Transform tab, make sure the [Name] column is highlighted, select "Replace values" leave the search for field blank and enter null in the replace with field (do not add quotes!). Now you should see nulls in the empty spaces (with a right alignment)

    Final step is right click the column header, select Fill, Fill Down

     

    Ps. If this helps solve your query please mark this post as Solution, thanks!

    It could solve this problem, but I'm getting this table as a result of some calculation inside power bi, working with data after power query stage. So it should some kind of "for like" cicle inside of power bi
