SharePoint Excel Services ODBC Driver

The Excel Services ODBC Driver is a powerful tool that allows you to connect with live Excel Services data, directly from any applications that support ODBC connectivity.

Access Excel Spreadsheet data hosted on SharePoint server like you would a database - read, write, and update data through a standard ODBC Driver interface.



Use node-odbc to execute SQL queries against SharePoint Excel Services data from Node.js.

Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser. With the CData ODBC Driver for SharePoint Excel Services, you can access live SharePoint Excel Services data from Node.js apps and scripts. In this article, we walk through installing node-odbc and the required tools to create a simple Node.js app with access to live SharePoint Excel Services data.

With built-in optimized data processing, the CData ODBC Driver offers unmatched performance for interacting with live SharePoint Excel Services data in Node.js. When you issue complex SQL queries from Node.js to SharePoint Excel Services, the driver pushes supported SQL operations, like filters and aggregations, directly to SharePoint Excel Services and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to SharePoint Excel Services Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

The URL, User, and Password properties, under the Authentication section, must be set to valid credentials for SharePoint Online, SharePoint 2010, or SharePoint 2013. Additionally, the Library property must be set to a valid SharePoint Document Library and the File property must be set to a valid .xlsx file in the indicated Library.

Building node-odbc

In order to connect to SharePoint Excel Services through the CData ODBC Driver, you need to build node-odbc manually (after installing the required tools).

Installing the Required Tools

The following commands install the tools required to build node-odbc (note the -g parameter, which installs the tools globally).

npm i -g windows-build-tools
npm i -g node-gyp

Building node-odbc

After installing the required tools, create a directory for the Node.js app and install odbc (which builds the binary for us to use in our Node.js script).

mkdir nodeodbc
cd nodeodbc
npm i -g node

Querying SharePoint Excel Services from Node.js

With the ODBC Driver installed, a DSN Configured, and node-odbc built, we are ready to query live SharePoint Excel Services data from a Node.js app. The sample code below connects to a specific DSN and queries the Account table.

myscript.js

const odbc = require('odbc');

async function queryExcelServices() {
    const connection = await odbc.connect(`DSN=CData ExcelServices Source`);
    const data = await connection.query('SELECT Name, AnnualRevenue FROM Account');
    console.log(data);
}

queryExcelServices();

Once you write the app, use node to execute the script:

node myscript.js
