6 Data Exchange Formats in Marketing Technology

Imagine you're traveling the globe with a suitcase full of your favorite gadgets. You have your smartphone, laptop, and camera. Each country you visit has its own type of electrical socket, different from your home country's sockets.

To ensure you can charge your devices wherever you go, you carry a set of adapters. Each adapter converts the shape and flow of electricity from the local socket into a form that your devices can accept, no matter where you are.

In the world of digital information, data exchange formats like CSV, JSON and XML serve a similar purpose as these adapters. Think of each software system as a country with its own unique "electrical socket" or way of handling data. Data exchange formats are the "adapters" that convert data from the format of one system into a format that another system can recognize and process.

Data Exchange in Marketing Technology

If you're a marketer who relies heavily on spreadsheets then you’re probably familiar with CSV files. CSV is simple: it stores data in plain text where each line represents a data record, and each record consists of fields or columns of data, separated by commas.

Now, consider CSV as a bridge between different marketing tools and platforms. For instance, you might export a CSV file from your customer relationship management (CRM) system and import it into an email marketing tool to send targeted campaigns. Or, you might take CSV exports from Google Analytics to combine with other data sources for a comprehensive report.

CSV is essentially one type of data exchange format, a category that includes other formats like JSON and XML. These formats serve a similar purpose: to transfer data efficiently between different systems and software, ensuring compatibility and usability across diverse platforms.

For a marketer, understanding these formats can enhance your ability to seamlessly integrate various marketing tools and platforms, making your workflow more efficient and expanding your capabilities to analyze, share, and leverage data to drive marketing decisions and strategies.

The 6 Data Exchange Formats

In marketing technology, CSV and JSON are the most common data exchange formats primarily due to their simplicity, wide support, and flexibility in handling various types of data.

However, as marketing becomes an increasingly technical field involving big data and AI, marketers are starting to encounter more varied data exchange formats coming from software engineering and data science.

Here's a breakdown of the 6 most common data exchange formats, each with its specific uses, advantages, and typical applications.

1. CSV (Comma-Separated Values)

Description: CSV is a text file format that uses commas as a delimiter to separate values. Each line—or row—of a CSV file is a data record, and each record consists of one or more fields, separated by commas.

Advantages: Easy to create and edit manually; widely supported by almost all data handling applications like spreadsheets, databases, and data processing tools.

Typical Uses: Data exporting/importing in applications like Excel, database management systems, and contact management systems.

Example:

firstName,lastName,email
John,Doe,[email protected]
Jane,Smith,[email protected]

2. JSON (JavaScript Object Notation)

Description: JSON is a text-based format based on two structures. First, a collection of key-value pairs which make up an Object. Second, an ordered list of values, also known as an array. Since these two data structures universal, JSON is highly interchangeable and supported by virtually all programming languages.

Advantages: Highly favored for its simplicity and speed in web environments. It is less verbose than XML and integrates seamlessly with JavaScript, making it ideal for web applications.

Typical Uses: Commonly used in web APIs, mobile applications, and AJAX-driven websites. The vast majority of web applications use JSON for handling requests to and responses from their APIs.

Example:

{
  "employees":
  [
    {
      "firstName": "John",
      "lastName": "Doe",
      "email": "[email protected]"
    },
    {
      "firstName": "Jane",
      "lastName": "Smith",
      "email": "[email protected]"
    }
  ]
}

3. XML (eXtensible Markup Language)

Description: XML is a markup language that uses tags to define data. Tags are written using angle brackets (‘<>’), and are used to indicate metadata such as column names. Data is enclosed in paired opening and closing tags. If you have worked with HTML before, XML is very similar as both are markup languages. However, while HTML was designed to display data, XML was designed to store and transport data.

Advantages: Extremely flexible in its ability to define data structures. It can be used to represent complex data structures and is very effective for long-term data storage and configuration files where readability is important.

Typical Uses: Used in enterprise applications, web services (SOAP), and configuration for various software applications and hardware devices.

Example:

<employees>

  <employee>

    <firstName>John</firstName>

    <lastName>Doe</lastName>

    <email>[email protected]</email>

  </employee>

  <employee>

    <firstName>Jane</firstName>

    <lastName>Smith</lastName>

    <email>[email protected]</email>

  </employee>

</employees>

4. YAML (YAML Ain't Markup Language)

Description: YAML is a human-friendly data serialization standard for all programming languages. It is highly readable and is sensitive to white space (uses indentation to denote structure).

Advantages: Excellent for configuration files and in applications where data is extensively handled by humans. It supports complex data structures and can manage details not easily handled by simpler data formats.

Typical Uses: Configuration files, in development environments, and applications needing detailed data structures like Docker containers or Kubernetes, as well as modern Infrastructure as Code (IaC) tools such as Terraform, AWS CloudFormation or AWS CDK.

Example:

employees:

  - firstName: John

    lastName: Doe

    email: [email protected]

  - firstName: Jane

    lastName: Smith

    email: [email protected]

5. Protocol Buffers (Protobuf)

Description: Developed by Google, Protobuf is a method of serializing structured data. It is useful in developing programs to communicate with each other over a wire or for storing data.

Advantages: Ensures backward compatibility and forward compatibility, making it ideal for applications that need to store and transmit large amounts of data with space efficiency.

Typical Uses: Mobile applications, communication protocols, and in high-performance environments like cloud services and internal data communication systems.

6. Parquet

Description: Parquet is a columnar storage file format available to any project in the Hadoop ecosystem. It is optimized for use with complex nested data structures.

Advantages: Parquet files offer very efficient compression and encoding schemes. The columnar storage format allows for better compression and more efficient reads. It supports advanced nested data structures and is ideal for handling large volumes of data in a distributive environment, such as big data processing systems.

Typical Uses: Widely used in data science and big data applications for storing large datasets. This format is especially beneficial when queries need to retrieve only a subset of fields in a large dataset, making reads faster and less costly in terms of computing power.
