Combine two or more rows in a csv using powershell

Question

I receive a file from one of our clients that looks like this: (I added headers to this to it for easier processing). Sample Input:

PlanID,Date,Transaction,T         


        

Answer 1

Import-Csv input.csv | Group-Object planid, transaction | 
Select @{n="PlanId";E={($_.name -split ',')[0]}},
       @{n="Date";e={($_.group)[0].date}}, 
       @{n="Transaction";E={(($_.name -split ',')[1]).trim()}},
       @{n="Type";e={($_.group)[0].type}},  
       @{n="Ticker";e={($_.group)[0].ticker}}, 
       @{n="Amount";e={($_.group | measure-object amount -sum).sum}},
       @{n="Cash";e={($_.group)[0].cash}} |
Export-Csv output.csv -NoTypeInformation

Steps:

1. Import the input.csv file
2. Group the objects by planid and transaction
3. Select the properties you want in your output
   1. PlanId = whatever is left of the comma in the name field of the object returned by group-object
   2. Transaction = whatever is right of the comma in the name field of the object returned by group-object
   3. Amount = sum of all amounts per grouped object
   4. Date = the date per grouped object
   5. Type = type per grouped object
   6. Ticker = ticker per grouped object
   7. Cash = cash per grouped object
4. Export the objects to output.csv (add notypeinformation to strip the top line with type info)
