Calculate Distance Between Two Addresses In Excel: A Step-By-Step Guide

Calculating the distance between two addresses in Excel might sound like a daunting task, but it’s actually quite straightforward! With the right tools and a step-by-step approach, you can easily find the distance between any two locations. Whether you’re planning a road trip, calculating delivery distances, or just curious, mastering this skill can add immense value to your Excel toolkit.

Getting Started: What You’ll Need

Before we dive into the process, here’s a quick checklist of what you need:

• Microsoft Excel installed on your computer
• Basic understanding of Excel functions
• Access to a geocoding service (like Google Maps API or others)

Step 1: Enable Developer Options

To use any external services like Google Maps, you’ll need to enable the Developer tab in Excel. Here’s how you can do it:

1. Open Excel and go to File > Options.
2. In the Excel Options window, select Customize Ribbon.
3. On the right side, check the box for Developer.
4. Click OK.

The Developer tab will now appear in the Ribbon.

Step 2: Obtain a Google Maps API Key

To calculate distances using Google Maps, you’ll need an API key. This is a unique identifier that allows you to use Google’s services. Here’s a simple way to get it:

1. Go to the and sign in with your Google account.
2. Create a new project.
3. Enable the Google Maps Distance Matrix API.
4. Go to Credentials and create an API key.

Important Note: Google’s API may require billing information, but they typically offer a free tier for basic usage.

Step 3: Set Up Your Excel Workbook

Now, let’s prepare your Excel workbook:

1. In column A, enter the starting addresses.
2. In column B, enter the destination addresses.
3. In column C, you’ll set up a formula to calculate the distance.

Example Setup:

Step 4: Write the VBA Code

Now, we will need to use a bit of VBA to make our API call. Here’s how to do it:

1. Go to the Developer tab and click on Visual Basic.
2. Insert a new module by right-clicking on any of the items in the Project Explorer and selecting Insert > Module.
3. Copy and paste the following VBA code into the module window:

Function GetDistance(startAddress As String, destAddress As String) As Double
    Dim http As Object
    Set http = CreateObject("MSXML2.XMLHTTP")
    
    Dim apiKey As String
    apiKey = "YOUR_API_KEY" ' Replace with your API Key
    
    Dim url As String
    url = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=" & _
          Application.WorksheetFunction.EncodeURL(startAddress) & _
          "&destinations=" & Application.WorksheetFunction.EncodeURL(destAddress) & _
          "&key=" & apiKey
    
    http.Open "GET", url, False
    http.Send
    
    Dim json As Object
    Set json = JsonConverter.ParseJson(http.responseText)
    
    On Error Resume Next
    GetDistance = json("rows")(1)("elements")(1)("distance")("value") / 1000 ' Distance in kilometers
    On Error GoTo 0
End Function

Make sure to replace "YOUR_API_KEY" with the actual API key you obtained earlier.

Important Note: This code uses JSON to parse the response, so you may need a JSON parsing library for VBA, such as "VBA-JSON".

Step 5: Use the Function in Excel

Now that you have your VBA function, return to your Excel sheet:

1. In cell C2, type the following formula:
   =GetDistance(A2, B2)

2. Press Enter, and the cell should now return the distance between the two addresses in kilometers.

3. Drag down the fill handle to apply the formula for other rows.

Common Mistakes to Avoid

While calculating distances between two addresses in Excel, here are some common pitfalls to avoid:

• Incorrect API Key: Make sure your API key is valid and has access to the Distance Matrix API.
• Address Formatting: Ensure addresses are formatted correctly. Even minor discrepancies can lead to errors.
• VBA Issues: If the function doesn’t work, double-check that the JSON library is correctly referenced.

Troubleshooting Tips

If you encounter any issues while using this method, here are some troubleshooting tips:

• Check for Errors in the API Response: Use the Immediate Window (Ctrl + G) in the VBA editor to print out the response and identify if there are issues with the request.
• Validate Addresses: Ensure both the origin and destination addresses are correctly spelled and formatted. You can test them directly in Google Maps to ensure they yield correct results.
• Check Internet Connection: Since this method relies on online APIs, ensure your internet connection is stable.
