This is what I am trying to accomplish but I can find no solutions:

I have one spreadsheet of AR for one customer, (downloaded from QB), which I have pared down to four columns: Invoice number, date, amount billed and status.
I have a second spreadsheet (downloaded from the customer) with six columns: Invoice number, date, amount, status, date paid and check number.

I need to merge/align the two spreadsheets so that the invoice numbers in both “A” columns match up with each other and all other data remains intact with that invoice number. So, I am envisioning, a row looking like this:
A1:invoice number, B1:date, C1:amount billed, D1:status (All pulled from spreadsheet 1), E1:invoice number, F1:date, G1:amount, H1:status, I1:date paid, J1:check number (All pulled from spreadsheet 2)

Of course, if there are no matches from the second spreadsheet to the invoice number in Column A, then Columns E thru J would be blank.

Thank you very much for any help with this issue.
