Connecting Excel to the Kudurru Stone API
This article walks you through pulling your Kudurru Stone data directly into Microsoft Excel using Power Query (Get & Transform). Once connected, you can refresh the data at any time with a single click, no manual exports required.
Before You Begin
- Your firm must have an active Premier Package subscription to use the Kudurru Stone API. If you are unsure, contact your account administrator.
- You will need an API key. If you have not generated one yet, see Creating an API Key before continuing.
- This guide requires Microsoft Excel for Microsoft 365. Power Query is built in — no additional software or downloads are needed.
Step 1 — Open the Power Query Web Connector
- Open a new or existing Excel workbook.
- Click the Data tab in the ribbon.
- Click Get Data → From Other Sources → From Web.
Note: If you do not see Get Data in your ribbon, your organization may have restricted this feature. Contact your IT administrator to enable Power Query.
Step 2 — Enter the API URL and Your Key
- When the dialog opens, select Advanced at the top (not Basic).
- In the URL parts field, enter:
- https://api.kudurrustone.com/api/v1/quotes
- Scroll down to HTTP request header parameters and click Add header.
- In the left box, type exactly:
X-Api-Key - In the right box, paste your API key.
- Click OK.

Step 3 - Filters and All Pages
- Click on Advanced Editor
- Paste in the Power Query code from above. This code will allow all pages to load and allow you to add filters to the data.
Tip: Be sure to replace the "YOUR_API_KEY_HERE" with your actual API Key
- Follow the Filtering section above on how to add filtering and refer to our API reference for the available filters. API Reference

Step 3 — Navigate to the Quote Data
Power Query will open and display the raw API response as a single record. Your quote records are nested inside the data field.
- In the Power Query editor, locate the row labeled data. You will see the word List to the right of it.
- Click List to drill into the quote records.
- In the ribbon, click the Transform tab, then click To Table.
- Leave the default settings in the dialog that appears and click OK.
Step 4 — Expand the Quote Fields
- Click the expand icon (the double-headed arrow) in the Column1 column header.
- Select the fields you want to bring into Excel. Please see the API Reference for available fields.
- Uncheck Use original column name as prefix to keep your column headers clean.
- Click OK.
Step 5 — Load the Data into Excel
- Click Close & Load in the Home tab of the Power Query editor.
- Excel will load your quotes into a new worksheet as a formatted table.
Your data is now live and connected to KudurruStone.
Refreshing Your Data
To pull the latest data from KudurruStone at any time:
- Click anywhere inside the table.
- Click the Data tab → Refresh All.
Excel will re-query the API and update the table automatically. You can also right-click the table and select Refresh.
Note: Your API key is stored inside this workbook's connection. Do not share workbooks containing API keys with people outside your firm.
