import HeadTitle from '@site/src/components/General/HeadTitle.tsx';

OpenBB Add-In for Excel allows you to access your data connectors from OpenBB Terminal Pro inside Microsoft Excel. This can be done using the OBB.BYOD function.

Single widget

=OBB.BYOD("widget_name")

:::info

• Make sure your widget is setup in the OpenBB Terminal Pro.

:::

Own backend

=OBB.BYOD("widget_name","backend_name")

If your backend supports it is possible to pass a symbol, a date or other optional parameters:

=OBB.BYOD("widget_name","backend_name","my_symbol","YYYY-MM-DD",{"param1":"value1","param2":"value2", ...})

:::tip The easiest way to pass optional parameters is to write them into cells and reference them in the function. For example, =OBB.BYOD(...,A1:B2) where A1 contains "param1", B1 "value1", A2 "param2", B2 "value2" and so on. :::

:::info

• Make sure your backend's CORS settings allow requests coming from https://excel.openbb.co.
• Requests via HTTP will be blocked by Excel. So if you are using the Add-in for Excel on Mac or Office on the web with Safari browser you need to run your backend via HTTPS.

:::

Native integrations

Supported native integrations:

• database
• snowflake

=OBB.BYOD("widget_name","native_integration")

:::info

• Make sure your OpenBB Data Connector is properly configured and the widget is setup in the OpenBB Terminal Pro.
• Native integrations are available only for Excel on the web or Windows.
