ARCH

This domain hosts the task pane files for ARCH, a Microsoft Excel add-in published by First Porter Inc.

There is nothing to use here. The add-in is loaded by Excel itself, from a manifest deployed through your organisation’s Microsoft 365 admin centre.

What is served from this domain

Static files only — the task pane page, its JavaScript modules and the ribbon icons. The same files are served to every organisation.

What is not

No customer data is stored, processed or transmitted here. Workbook contents never leave the user’s device. The add-in builds its workbooks in code and retrieves nothing at runtime.

Third-party code

None. This page loads no scripts, fonts or external resources of any kind.
