Turning alternate rows into columns - Power Query/M Function
So I have some messy data coming from pdf invoices which I have 95% cleaned how I want, but I cannot work out the last step.
I am copying the data into a table with ctrl a/c/v and it spits it into a single column.
This is fine, using conditional columns etc in PQ I can get data to look like table on left in below pic.
I want it to end up like table on right. Playing with transpose/unpivot/pivot/split doesn't seem to get me the results I want.
I'd strongly prefer a solution in PQ, but if I have to use regular formulas I can work it out. This will be a monthly task, and invoice size will vary.
Any thoughts? I feel like I've missed something obvious.
davidmaddock54 The attached workbook contains a working query that does what you asked for. I trust you can get it to work in your own schedule.
It involves adding an Index column from zero. Then a Modulo of 2 on the Index, creating a column with alternating zeroes and ones. Pivot the Modulo column without aggregation of Column1 and do some cleaning up.

One more variant for the collection
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content], Items = Table.AlternateRows(Source,1,1,1), Values = Table.AlternateRows(Source,0,1,1), Result = Table.FromColumns( {Items[Column1], Values[Column1]}, {"Value", "Item"} ) in Result- Thank you. More options and chances to work with M functions the better. There's a few more things I may need from this info, might be handy to have alternative options.

- Oh, scrap that, errors on work computer, but it shows on my own laptop. Handy. I can do some comparisons and make sure I go step by step.
Thanks again.- And it works. Set up now.
- Thanks so much. I get an error when I open the query editor, but I think I can follow the steps in the formula bar. It certainly spits out what I want at the end.
