Ledger Import

Import accounting transactions from a CSV file into Ledger, using naive Bayesian learning to identify accounts from each payee. Heavily inspired by the Reckon Ruby gem.

Ledger is a powerful, double-entry accounting system that is accessed from the UNIX command-line.


Installing Ledger

The simplest way to install Ledger 3 is through Homebrew.

brew install ledger --HEAD

The --HEAD option is required to install version 3.x.
