Top 10 Best Data Transformation Tools in 2022

Today, to survive and stand out amongst your competition, you have to make data-driven decisions. In order to do that, you need to be collecting and analyzing as much information as possible. But how can you do that in the most efficient way?  Data transformation tools are one of the weapons you have in your arsenal to enable you to make sense of your raw data.

Why do you need data transformation tools?

In the data world and in computer science in general, there is a concept called garbage in, garbage out, or GIGO for short. This principle suggests that if your input data is garbage (or in this case unstructured, flawed, or cluttered) then you will get nonsense output (e.g., garbage, or in this case, bad decisions).

Data transformation tools help you with exactly that. They simplify the process of changing the structure or values of data so they end up in the appropriate format for analysis. This process is critical in order to extract actionable insights from your data and improve your business or even your life.

Data transformation tools are growing in popularity for this exact reason and in this article, we will number the top-10 data transformation tools you can use to boost your data analytics projects and eventually improve your business decisions.

The list of top data transformation tools to use in 2022

Power Query is the easiest way to connect, extract, transform, and load data from a wide range of sources.

Features

Using Power Query you can seamlessly access data stored in various sources and reshape it, all without any use of code. It supports a wide range of connectors, such as REST APIs, databases, analytics platforms, cloud providers, and many more. If you have a programming background, you can even use Power Query SDK to build your own custom connector.

With more than 300 transformations, you can manipulate your data as per your requirements and load them into popular BI tools such as PowerBI. And the most amazing thing is that you can do all of these without writing a single line of code and by using software that you know.

Pricing

Power Query comes with Microsoft Excel by default. This means that in order to use it you will need to acquire a Microsoft Excel license.

Currently, this is doable by purchasing a Microsoft 365 license which starts from $69.99/year or $6.99/month. If you buy the family package (for 2-6 people), it’s $99.99/year or $9.99/month and you can even try it for free for 1 month.

Coupler.io

11 coupler logo

Coupler.io is a no-code data importing solution which allows you to pull data from multiple sources and load it to a few destinations. For example, you can automate the export of datasets from Airtable to your Excel workbook every Friday without a single line of code.

Coupler.io is not a data transformation tool, but you can use it in combination with some of those mentioned above, for example, Excel Power Query. In addition, for some integrations, Coupler.io provides data transformation functionality, such as filtering, selection of columns, etc.

Features

Automatic data refresh is the main benefit you can get with Coupler.io. This means that you can automate data flow on a custom schedule, for example, every hour from Monday to Friday. This feature is available to all users on all subscription plants.

In addition to the capability to select how often your data is refreshed, you can also change the import mode from Replace to Append. The former fully replaces the data with the newly imported records, while the latter adds the new rows to those that were imported before. This is quite useful for making a history log of changes to your data and simply for backup purposes.

Pricing

Coupler.io comes with a 4-tier pricing model to meet every need. Specifically:

  1. Free: This tier is free forever and ideal for users with a side hustle that want to automate their data import. It offers an unlimited set of users and integrations, 100 monthly runs with a thousand rows per run, and an hourly automated data refresh.
  2. Professional: This tier works best for individuals with an increased need for import rows. It costs $24 per month and increases the Free tier’s runs to 2,500 with 10,000 rows per run.
  3. Squad: Ideal plan for small teams who collaborate on multiple sources. It costs $49 per month providing 5,000 monthly runs with up to 50,000 rows per run. Additionally, you can schedule an automated data refresh every 30 minutes.
  4. Business: The largest tier which is perfect for companies with multiple teams. With $99 per month, you can have 25,000 runs per month with more than 100,000 rows per run and you can schedule your automated data refresh to run every 15 minutes.
