11 ETL tools to consider in 2025
ETL, or Extract, Transform, Load, is fundamental in the realm of data analytics. It is a process achieved through a single tool or set of tools that, first, extracts data from various sources like databases, spreadsheets, or even the internet. Then, it skillfully transforms the data, cleans it up, reorganizes it, and ensures it’s ready for analysis. Finally, ETL tools load this refined data into a central location, such as a data analytics platform, where businesses can readily access and analyze it.
ETL is the essential workhorse that guarantees data used for vital decisions is accurate, consistent, and prepared for action. These tools enable businesses to harness the full potential of data analytics.
What are ETL tools?
ETL tools are like specialized assistants in the world of data analytics. They are software applications designed to streamline and automate the Extract, Transform, Load (ETL) process. These tools make it easier to pull data from diverse sources, such as databases, files, or web services. Then, they provide functions to transform the data, so it’s clean, consistent, and ready for analysis that combines data across different sources. Finally, ETL tools facilitate the load process, efficiently moving the transformed data to a centralized location, like a data warehouse, business intelligence (BI) platform, or data-specific applications.
Types of ETL tools
There are various types of ETL tools tailored to different business needs and budgets.
- Enterprise ETL tools: These are robust, commercial ETL solutions offered by companies like Informatica, Domo, and Microsoft SSIS. They are known for their comprehensive features, scalability, and support, making them ideal for large organizations. These tools specialize in working with hundreds to thousands of data sources and support complex data integration needs.
- Open-source ETL tools: Open-source tools like Apache NiFi and Talend provide flexibility and cost-effectiveness. They are favored for their community-driven development, allowing users to modify and extend functionalities. These tools are suitable for businesses seeking budget-friendly options and customization.
- Cloud-based ETL tools: Cloud services like AWS Glue and Google Dataflow offer ETL capabilities as a service. They are highly scalable, serverless, and eliminate the need for infrastructure management. Cloud-based ETL tools are ideal for businesses operating in cloud environments, offering easy integration with already-established cloud data storage and analytics services.
- Custom ETL tools: Some organizations develop custom ETL solutions tailored to their specific needs. These tools are designed in-house and offer precise control over data integration processes. Custom ETL tools are suitable for unique business requirements but often require significant development effort and ongoing maintenance. Often, organizations that work extensively with highly sensitive data like personal health information (PHI) will utilize custom internal ETL tools to better manage security and specific transformation requirements.
How do ETL tools work?
ETL tools follow a three-step process, and it’s all in the name — extract, transform, load.
Extraction
It’s difficult to find a modern organization that only uses one source of data, and many organizations use multiple data analysis tools, too. The first step in the process is extracting data from its source. Sources include but certainly are not limited to:
- Sales and marketing applications
- Data storage platforms
- Analytics tools
- Data warehouses
- Mobile apps and devices
- On-premise data storage
- Cloud data storage
- Databases
- CRM systems
ETL tools gather raw data, structured and unstructured, into a single location and consolidate it.
Transformation
The second step in the ETL process applies an organization’s rules and regulations to the data to make it meet requirements and be easily accessible. The transformation process includes:
- Cleaning the data to resolve inconsistencies and missing values.
- Standardizing the data to a predetermined format.
- Excluding or discarding redundant data.
- Removing unusable data from the data set and flagging any anomalies.
- Organizing data by type.
This step is arguably the most important part of the ETL process because it improves the quality and integrity of the data an organization collects.
Loading
Last but not least, transformed data is loaded into a new destination. This could be a solution like Domo or a standard data warehouse. Depending on the ETL tool, data may be loaded in one large batch or at scheduled intervals.
A word on extract, load, transform (ELT) methodology
Extract, load, transform (ELT) tools have the same purpose as ETL tools but the process is slightly different. ELT loads data into the central repository immediately after extraction instead of waiting to transform it. This approach is becoming popular with the rise of cloud storage instead of on-premise solutions, but ELT is still a relatively new process and tools are still evolving. Some organizations need both ETL and ELT tools for gathering data.
How to choose an ETL tool
When selecting an ETL platform for your business, several key factors should guide your decision-making process. These include considering the types of data sources you need to integrate, evaluating the costs associated with the platform, and assessing its capabilities to ensure it aligns with your specific data integration requirements.
Data Sources
Before choosing an ETL platform, it’s essential to identify the variety of data sources your business relies on. These sources could range from databases and spreadsheets to cloud-based applications and web services. Ensuring that your chosen platform can effectively connect and extract data from these sources is crucial for a seamless data integration process. Compatibility with your existing data ecosystem is paramount to prevent integration challenges down the road.
Cost
Evaluate the total cost of ownership, including licensing fees, maintenance, and potential scalability expenses. It’s essential to strike a balance between your budget constraints and the capabilities of the platform. Some platforms offer cost-effective and open-source options, while others provide comprehensive features at a higher cost. Choose a pricing model that aligns with your business’s financial resources and growth projections.
Capabilities
Look for features such as data transformation and cleansing tools, scalability to handle increasing data volumes, support for real-time or batch processing, and compatibility with data warehousing and analytics tools. Additionally, consider user-friendliness, as ease of use can significantly impact your team’s productivity. Prioritize capabilities that directly address your data integration requirements, both in terms of current needs and future scalability.
