Modern advanced marketing analytics is hard to imagine without ETL tools. After all, before a company starts building reports and searching for insights, all the data they collect from disparate sources must be processed: cleaned, verified, brought into a single format, and combined. In this article, we detail the top 15 ETL softwares for 2023 so you can choose the best one for your business.

What is ETL?

ETL (Extract, Transform, Load) is the data integration process that underpins data-driven analytics. It consists of three steps:

  1. Data is extracted from the original source.

  2. Data is then transformed into a format suitable for analysis.

  3. Finally, data is loaded into storage, a data lake, or a business intelligence (BI) system.

ETL provides the foundation for successful data analysis and a single source of truth to ensure that all enterprise data is consistent and up to date.

What are ETL tools?

ETL tools are services that help you execute  the Extract, transform, and load process. Simply put, ETL softwares allow companies to collect data of various types from multiple sources, convert it into a single format, and upload it to a centralized repository such as Google BigQuery, Snowflake, or Azure.

What are the benefits of ETL tools?

  • Save time and eliminate manual data processing. ETL tools help you collect, transform, and consolidate data automatically.

  • Make it easy to work with a large amount of complex and diverse data: time zones, client names, device IDs, locations, etc.

  • Reduce the risk of data errors caused by human factors.

  • Improve decision-making. By automating work with critical data and reducing errors, ETL ensures that the data you receive for analysis is high-quality and trustworthy.

  • Because you save time, effort, and resources, the ETL process ultimately helps you increase your ROI.

Let’s consider types of ETL tools.

Types of ETL tools

All ETL tools can be roughly divided into four types depending on their infrastructure and the supporting organization or vendor. Some are designed to work in the local environment, some in the cloud, and others both locally and in the cloud.

1. Cloud-based ETL tools

Cloud-based ETL tools extract data from sources and load it directly into cloud storage. They can then transform this data using the power and scale of the cloud. This is essentially a modern approach to the familiar ETL process, in which data transformation occurs after data is loaded into storage.

Traditional ETL tools extract and transform data from different sources before loading it into the warehouse. With the advent of cloud storage, there is no longer a need for data cleaning at an intermediate stage between the source and the target storage location.

Cloud-based ETL tools are especially relevant for advanced analytics. For example, you can load raw data into a data lake and then combine it with data from other sources or use it to train predictive models. Saving data in its raw format allows analysts to expand their capabilities. This approach is faster because it harnesses the power of modern data processing engines and reduces unnecessary data movement.

2. Enterprise ETL tools

These are ETL tools developed by commercial organizations and are often part of larger analytics platforms. The advantages of enterprise ETL tools include reliability and maturity, as they have been on the market for a long time. They may also offer advanced functionality: a graphical user interface (GUI) for designing ETL flows, support for most relational and non-relational databases, a high level of customer support, and extensive documentation.

In terms of minutes, enterprise ETL tools are usually more expensive than alternatives, require additional training for employees, and are difficult to integrate.

3. Open-source ETL tools

These are free ETL tools that offer a GUI for creating and managing data flows. Thanks to the open-source nature of these services, users can understand how they work and can extend their functionality.

Open-source ETL tools are a budget alternative to paid services. Some do not support complex transformations and may not offer customer support.

4. Custom ETL tools

These are ETL tools that companies create themselves using SQL, Python, or Java. On the one hand, such solutions have great flexibility and can be adapted to business needs. On the other hand, they require a lot of resources for their testing, maintenance, and updating.

What are the criteria for choosing ETL tools?

When choosing an ETL tool, you should consider your business requirements, the amount of data to be collected, the sources of that data, and how you will use it.

What to pay attention to when choosing an ETL tool:

  • Ease of use and maintenance.

  • Speed of the tool.

  • Data security and quality. ETL tools offering data quality audits help identify inconsistencies and duplicates and reduce errors. Monitoring features can warn you if you’re dealing with incompatible data types and other issues.

  • Ability to process data from many different sources. One company can work with hundreds of sources with different data formats. There can be structured and semi-structured data, real-time streaming data, flat files, CSV files, etc. Some of this data is best converted in batches, while other data is best handled through continuous streaming data conversion.

  • The number and variety of connectors available.

  • Scalability. The amount of data collected will only grow over the years. Yes, you might be fine with a local database and batch uploading right now, but will that always be enough for your business? It’s ideal to be able to scale ETL processes and capacity indefinitely! When it comes to making data-driven decisions, think big and fast, and take advantage of cloud storage services (like Google BigQuery) that allow you to quickly and inexpensively process large amounts of data.

  • Ability to integrate with other data platform components, including warehouses and data lakes.

Now that we have covered the types and features of ETL tools, let’s take a look at the most popular of these tools.

Key takeaways

The volumes of data collected by companies are getting bigger every day and will continue to grow. For now, working with local databases and batch loading is enough, but very soon, this will no longer satisfy business needs. Thus, the ability to scale ETL processes is convenient and especially relevant for advanced analytics.

When it comes to choosing an ETL tool, think about the specific needs of your business. If you are working locally and your data is predictable and comes from only a few sources, then a traditional ETL tool will be enough. But don’t forget that more and more companies are moving to a cloud or hybrid architecture.
