fetch.rb: Downloads receipts from IMAP servers and intelligently saves them into PDF files.
extract.rb: Parses PDF files and extracts supplier, invoice date and amount into a tab-separated output.
Edit fetch.rb to add your IMAP server data and the appropriate filters and extractors for your use case. Edit extract.rb to add the additional parsers for the generated PDFs as needed.
Run fetch.rb. It will save PDF files to the current working directory, named with timestamp, sender and message ID.
Then, run extract.rb passing the PDF files as args and redirecting the output to a .tsv file.
Open the .tsv file with Excel and copy-paste to your heart’s content.
