Motivation

In the past decades the author used different personal accounting tools:

• Quicken
• Microsoft Money
• Lexware Finanzmanager
• BankingZV

the pain the conversion between those tools created was finally big enough to do something about it.

Goals

• use a computer and human readable ledger format that is ready to survive decades
• convert from and to the formats of the tool of choice
• allow for simple sanity checks and reports
• allow for systematic tidy up
• allow for integration into a larger organizational knowledge graph

Hub & Spoke Conversion

The pyNomina tool follows a Hub and Spoke model for conversion between different personal accounting file formats. The Ledger Book (YAML/JSON) format acts as the hub, with each supported format serving as a spoke. This setup simplifies conversions by allowing data to be transformed from any spoke to the hub and then to any other spoke format.
