Installation Guide
This guide explains how to install the ExForms Data Transfer add-in for Microsoft Excel. There are three installation methods:
| Method | Best For | Requirements |
|---|---|---|
| Microsoft Store | Individual users, quick setup | Microsoft 365, Excel 2016+ |
| Manual (XML Manifest) | Single user, when Store is unavailable | Excel 2016+, local shared folder |
| Microsoft 365 Admin Center | Organization-wide deployment | Microsoft 365 admin access |
Method 1: Microsoft Store (Recommended)
The easiest way to install the ExForms Data Transfer add-in is directly from the Microsoft Office Add-ins Store.
Direct links: open the Microsoft Marketplace listing (works on Windows, Mac, and Excel on the web), or use the one-click installer office.exceltoforms.com/install/exforms (choose Excel desktop or web). You can also search the Store from inside Excel, as shown below.
Step 1 – Open the Add-ins Menu
- Open Microsoft Excel
- Go to the Home tab in the ribbon
- Click Add-ins (or Get Add-ins depending on your Excel version)

Step 2 – Search for ExForms
- In the Office Add-ins dialog, click on Store
- Type "ExForms Data Transfer" in the search box
- Press Enter to search

Step 3 – Add the Add-in
- Find ExForms Data Transfer in the search results
- Click the Add button
- Accept any permissions if prompted
Step 4 – Start Using ExForms
Once installed, you can access the add-in:
- Go to the Data tab in Excel's ribbon
- Click the ExForms Data Transfer button to open the task pane

✅ You're ready! Proceed to the Navigate the Add-in guide, the PDF Forms Guide, or the Word Documents Guide to start using ExForms.
Buying a plan: Microsoft or FastSpring
Installing the add-in is free. Advanced features run on a paid plan, and you can buy one two ways — pick the one that fits your account and region:
| Microsoft (AppSource / Marketplace) | FastSpring (direct) | |
|---|---|---|
| Account types | Microsoft work or school accounts only — personal Microsoft accounts are not supported | Any account, including personal email |
| Regions | Available only in tax-remitted markets (the regions Microsoft collects and remits tax for) | Worldwide |
| Billing | On your Microsoft invoice | Card / PayPal via FastSpring |
| Best for | Organizations already on Microsoft 365 in a supported region | Personal users, or anyone in a region or account type Microsoft doesn't cover |
Not sure which to pick? If you sign in with a personal email, or your country isn't listed when you try to buy through Microsoft, use FastSpring — it works for any account, anywhere. Buy or manage a plan from your ExForms account (see pricing).
Method 2: Manual Installation (XML Manifest)
If the Microsoft Store is not available or you prefer manual installation, you can install the add-in using an XML manifest file. This method creates a shared folder on your local computer that Excel can recognize as a trusted add-in catalog.
📝 Note: Excel's Trust Center does not accept local file paths (like
C:\folder), but it does accept shared folder paths (like\\YOURPC\folder). That's why we share the local folder—to get a network-style path.
Step 1 – Create an Add-In Folder
Create a folder on your local computer to store the add-in manifest.
Example:
C:\ExFormsAddin\
💡 Tip: Choose a location you won't accidentally delete.
Step 2 – Download the XML Manifest File
Download the ExForms manifest file:
Or copy this URL directly:
https://exceltoforms.com/ExFormOfficeAddInExcelUI.xml
Step 3 – Save the XML File
Save the ExFormOfficeAddInExcelUI.xml file in your Add-In folder:
C:\ExFormsAddin\ExFormOfficeAddInExcelUI.xml
Step 4 – Share the Folder
Share the folder to get a network-style path that Excel's Trust Center will accept.
- Right-click the Add-In folder (e.g.,
C:\ExFormsAddin) - Click Properties
- Go to the Sharing tab
- Click the Share... button

- In the dialog, select your username (or "Everyone" for simplicity)
- Click Share, this will open the Share menu, you have to click Share in there:

Step 5 – Copy the Network Path
After sharing:
- Open the folder's Properties again
- Go to the Sharing tab
- Copy the Network Path shown (e.g.,
\\YOURPC\ExFormsAddin)

📋 Save this path – you'll need it in the next step. The path will look like
\\COMPUTERNAME\FolderName.
Step 6 – Open Excel Trust Center Settings
- Open Microsoft Excel
- Go to File → Options
- Click Trust Center in the left sidebar
- Click Trust Center Settings...

Step 7 – Add Trusted Add-in Catalog
- In the Trust Center, click Trusted Add-in Catalogs
- In the Catalog Url field, paste the network path you copied
- Click Add catalog

Step 8 – Enable "Show in Menu"
- Find the catalog URL you just added in the list
- Check the Show in Menu checkbox next to it
- Click OK

Excel will display a message that changes will be applied on the next restart.
Step 9 – Restart Excel
