Version 1.01 of NZ Chart of Accounts.

Download contains the source spreadsheet, and output CSV file that is loaded into Openbravo.

 It's the first cut, so has some rough edges, but it does load into OB, allowing you to get underway.  (In Openbravo you can't create a new company data set without a chart of accounts, so you need a basic chart to get started, even if you subsequently completly change it).
