About x0

x0 connects Xero to Excel and the tools around it — Power Query, Power BI, OData, REST, and (on Professional) a read-only Postgres warehouse.

We turn Xero’s nested API shapes into flat, refreshable tables so you stop exporting CSVs and start refreshing live books.

Building a Xero client? The hosted Xero API simulator is a read-only drop-in for api.xero.com — an extra feature of Professional, used in our own CI and available to Pro customers.

Built in New Zealand. Operated from Wakefield, Tasman. See the team, pricing, or contact us.
