CData Connect

Fully-integrated Microsoft Excel Add-Ins that connect Excel with live data.



Execute MySQL queries against Excel data from Node.js.

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

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Excel, allowing you to easily query live Excel 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, leveraging server-side processing to quickly return Excel data.

Create a Virtual MySQL Database for Excel 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" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Excel.

    The ExcelFile, under the Authentication section, must be set to a valid Excel File.

  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 data from any MySQL client.

Query Excel from Node.js

The following example shows how to define a connection and execute queries to Excel 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 (exceldb)

Connect to Excel 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 : 'exceldb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Sheet', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
