🧭 Page Explorer for Business Central: everything a page hides, in plain sight
Page Explorer is an AL extension that displays all fields and actions available on a Business Central page in a single window, showing their current values, descriptions, and tooltips. It uses the native Page Summary Provider codeunit to parse page metadata and helps users understand page structure and available options.

"The pattern is always the same: a pageextension that adds the action in processing and passes the corresponding Page:: together with the record's SystemId."
Key points
- Displays fields with current values and descriptions, plus available actions with tooltips in a side-by-side interface
- Built on Page Summary Provider codeunit and Page Action table 2000000143 included in Business Central
- Provides a ‘With Value Only’ filter to show only populated fields and a debug view showing raw JSON
- Extended via pageextensions that add a Page Explorer button to any page by passing the page ID and record SystemId
- Includes pre-built extensions for Customer Card, Vendor Card, Item Card, and Sales Order pages
Quotes
- “The pattern is always the same: a pageextension that adds the action in processing and passes the corresponding Page:: together with the record’s SystemId.” (Shows the reusable pattern that makes the extension easily extensible to any page without duplicating core logic.)
