Clearing the app cache (local storage + cached network files) can help resolve issues like incorrect data, missing UI elements, or unexpected behavior. The steps below walk you through fully resetting the ExtendInsights add-in inside Excel.
Prerequisites
Before you begin:
Close any unsaved work in Excel.
Make sure you are comfortable using the Inspect (Developer Tools) window.
These steps apply to the ExtendInsights add-in running inside Excel.
Why Clearing the App Cache Helps
ExtendInsights runs in a browser-like environment inside Excel. Over time, this environment may store:
outdated scripts
cached API responses
saved session data
corrupted local storage
Clearing the app cache forces the add-in to reload everything fresh.
How to Clear the App Cache
Follow these steps in order to ensure a complete reset.
Step 1: Open Developer Tools
Open Excel and launch the ExtendInsights add-in.
Right-click anywhere inside the add-in panel.
Click Inspect.
A debugger window (Developer Tools) will open.
💡 This window lets you access storage and caching controls used by the add-in.
Step 2: Clear Local Storage (Important)
This removes stored settings and app-specific data.
In the debugger window, select the Application tab.
In the left menu, expand Local Storage.
Click the CloudExtend URL listed under Local Storage.
Right-click and choose Clear.
📝 This resets the add-in’s stored state, including session data and preferences.
Step 3: Clear Cached Network Files
This ensures ExtendInsights reloads the latest scripts and UI.
Go to the Network tab.
Check the box for Disable cache.
Press CTRL + R (Windows) to force a hard reload.
⚙️ This reloads the add-in from the server instead of using stale cached files
Step 4: Restart Excel
Completely close all Excel windows.
Reopen Excel.
Launch the ExtendInsights add-in again.
🎉 The add-in will now load with fresh data and clean cache.
When Should You Do This?
Clear the app cache if you notice:
The add-in won’t load or freezes
Missing or outdated fields/UI
Authentication loops or login errors
Data not refreshing correctly
Issues immediately after an update
This is a safe and effective first troubleshooting step.
