10 Best Data Transformation Tools [2024]

Not all data are created equal. For example, both HubSpot and Salesforce are CRM platforms. But they don’t have the same data structure and format. Or they even use different naming conventions, APIs, and more. To integrate data from both, you need to do some data transformation. And that’s where data transformation tools come in. 

Data transformation is part of  data pipelines  like ETL and ELT. If all data have the same structure, types, and formats, there’s no need for the ‘T’ in these data pipelines. 

So, if you’re on a quest to look for tools that offer easy but flexible data transformation, seek no more. This article contains curated information from reputable sources to give you options. We included only the tools with very positive feedback from their users. 

Here’s what we are going to discuss: 

  1. The Definition of Data Transformation
  2. The 10 Best Data Transformation Tools
  3. Conclusion 

Let’s dive in and compare data transformation tools.

The Definition of Data Transformation

Data transformation is the process of converting data from one format to another. 

To explain how it works, let’s compare it to translating a book. An author may have started writing his masterpiece in English. But he wants to capture another language group. Let’s say Spanish. So, the author hires a translator. The translation of the text is like converting data from one format to another. Once done, a Spanish reader can understand the translated book. Likewise, a different app or system can use the transformed data. 

Data transformation also helps in cleaning, filtering, summarizing, and reshaping data. For example, a stakeholder doesn’t need a lot of details. Only the summary matters. So, you perform data aggregation like sum, average, or the like. Another example is redundant entries in your data. You don’t want this spoiling your stakeholder’s data-driven decisions. So, you remove these unwanted duplicates. 

But what should you look for in tools for data transformation? 

The best data transformation tool for you is one that is simple and fast. But it should be flexible enough that it can handle your unique requirements. Some tools offer a graphical interface with components and templates you can use. Others use formulas. And even others allow you to code. But some tools have them all. 

So, let’s start our list of data transformation tools.
