CData Connect



Execute MySQL queries against Excel Online data from Node.js.

You can use CData Connect Cloud to query Excel Online data through a MySQL interface. Follow the procedure below to create a virtual database for Excel Online in Connect Cloud and start querying using Node.js.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Excel Online, allowing you to easily query live Excel Online data in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Excel Online, leveraging server-side processing to quickly return Excel Online data.

Create a Virtual MySQL Database for Excel Online Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Cloud and click Databases.
  2. Select "Excel Online" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Excel Online.

    You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:

    • Workbook: Set this to the name or Id of the workbook.

      If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.

    • UseSandbox: Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.

    You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Excel Online data from any MySQL client.

Query Excel Online from Node.js

The following example shows how to define a connection and execute queries to Excel Online with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Connect Cloud (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on Connect Cloud
  • Database name: The database you configured for Excel Online (excelonlinedb)

Connect to Excel Online data and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'excelonlinedb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Test_xlsx_Sheet1', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
