Import data to modify existing posts
I would like to import data to modify posts. I get a file from my bank with details about paid invoices. Predefined rows in this file include a refernce number which is my Filemaker invoice number. For those matching invoices I want to set stats to "Paid" and write current date. Here is an example of the file. Rows starting with "20" contains Invoice number in positions marked with red. Is it possible to do this? Maybe I have to pre-process the file fisrt?
