Summarize with AI:

TL;DR

This guide compares 13 data preparation tools for turning raw source data into something analysable.

Integration-led: Airbyte and Integrate.io move and stage data first, pairing with dbt for transformation in the warehouse.
Analyst self-service: Alteryx, Altair, Datameer, Microsoft Power BI, Qlik and Tableau let analysts clean and shape data without engineering support.
Enterprise platforms: Informatica, Talend, TIBCO, Gathr and SAP Data Intelligence Cloud add governance, lineage and scale.
Why it pays off: better data quality, more accurate ML models, sharper insights and far less time lost to rework.

Data preparation tools clean, reshape and standardise raw data so it can actually be analysed. Raw data arrives from many sources with different structures, schemas and types, which makes it unreliable as an analysis input no matter how good your BI layer is. The thirteen tools below cover that work, from analyst-facing cleaning to enterprise pipelines.

Data preparation is a process of preparing raw data for further management and analysis. It is a pre-processing technique that includes collecting, cleaning, and structuring raw data.

Data preparation is an iterative process that becomes time-consuming if done manually. According to a Forbes survey, data scientists spend 80% of their time on data preparation and management. You can speed up this process using data preparation tools.

This article gives you a comprehensive list of popular data preparation tools that you can use to fine-tune your data.

FAQs

1. Is data prep an ETL tool?

No, data prep is not essentially an ETL tool and vice versa. Both data preparation and ETL involve transforming data into a format acceptable to the destination system. However, they may differ in various aspects.

ETL tools facilitate data extraction from multiple sources, transformation to ensure data accuracy and loading of data into a unified location. Whereas, data preparation tools focus on cleaning and transforming data to uncover hidden insights.

2. What is the preparation of data analysis tools?

Data preparation is the process of collecting, cleaning, and transforming raw data into usable form. Some data analysis tools also facilitate data preparation by supporting data cleaning, transformation, integration, and visualization features. Alteryx, Microsoft Power BI, and Tableau are some examples of such tools.

3. What is the Dataprep tool?

You can also access a summary of changes made to your datasets with the help of a report generated by Dataprep.

4. What is an example of data preparation?

Consider an instance where you want to analyze e-commerce datasets containing sales, customer, product, and order data. You must first consolidate this data into a single dataset for data preparation. Clean this dataset by handling missing and duplicate values and correcting inconsistencies. You can then transform this data using processes such as aggregation and normalization.

Then, enrich this dataset by adding product ratings, customer segmentation, or competitor data. After this, validate it by checking for outliers and anomaly data records. This completes your data preparation process, giving you clean and consistent data for your e-commerce platform.

5. What is a test data preparation tool?

Test data preparation tools are software that generates and manages test data to check the performance of applications in development. They help identify and fix any discrepancies in software applications' data workflows.
