PayPal: Export a day of balance activity to CSV

See more PayPal Examples

Create a UTF-8 ledger export for the previous UTC day. Preserve signed amounts and separate currencies, and leave absent fees blank. The file is written after all pages have been read. Transaction Search can lag by several hours.
