Overview
The Joiin Integrations page is where you'll find everything you need to connect Joiin with the other tools and services you use. Each integration is listed as a tab across the top of the page — click on any tab to see an overview of that integration and guidance on how to get connected.
The integrations available are as follows:
Excel Add-in
The Joiin Add-in for Excel is available from the Microsoft App Store and lets you use Joiin-specific functions directly within Excel. Pull live consolidated data — Trial Balance, P&L, Balance Sheet and more — straight into your spreadsheets using simple formulas such as =JOIIN.BS(...), with full control over companies, currency, and date range.

Public API
The Joiin API is a RESTful API that lets you programmatically query data from Joiin or import data into Joiin. Use it to build custom integrations, connect to tools such as Power BI, or write your own code against your consolidated financial data.
