What is Data Wrangling? Definition, Tools, and Benefits

Raw data contains various errors and is incomplete to read. Therefore, such data needs to be transformed into a readable format, which organizations can use to derive meaningful insights. The data wrangling process allows the raw data to be converted into an accurate format to ensure high-quality data. 

This saves many organizations and helps them make informed decisions based on data. So, today, let’s see what is data wrangling and how it helps businesses maximize their efficiency.

What is Data Wrangling? 

Data wrangling is also known as data munging and differs from data mining. Data wrangling is a data analytical process that involves cleaning, structuring, and enriching raw data into a readily usable format for analysis. The process requires precise data cleaning by removing and correcting errors, inconsistencies, and duplication. 

Properly structuring data into a tabular format makes the data analysis process easy. The definition of what is data wrangling continues beyond here. It includes merging and formatting data sets to prepare data for further data analysis, machine learning projects, modeling, and exploration. So, it is a systematic and transformative way of structuring messy and unstructured data. 

Why is Data Wrangling Important in 2024?

The data wrangling process continues to grow in 2024 for various reasons. Today, many professionals spend 73% of their time wrangling data. This shows that data processing is indispensable, and it helps businesses to make concrete bases by making timely and informed decisions. 

Some of the reasons why data wrangling is significant in 2024 are as follows:

  • Volume and variety of data: Today, companies can generate data from the internet, social media, IoT devices, and various other sources. This data needs to be managed and analyzed correctly to increase performance exponentially. Data wrangling is the fastest means to handle these data and ensure data efficiency.
  • Advanced analytics and Artificial Intelligence: Advancements in analytics and AI have caused high demand in data processing. Data wrangling has also become much easier with some efficient tools to advance the models, clean them accurately, and convert them into better-structured forms. Data wrangling will help in future AI and machine learning projects to maximize the profitability of businesses.
  • Faster decision-making: In this fast-paced world, you must make quick decisions and stay competitive. Data wrangling ensures that businesses make appropriate decisions based on data. It prepares data so that companies can analyze them and gain information quickly.
  • Compliance and data governance: Businesses are required to maintain data privacy and usage regulation as per GDPR and CCPA guidelines. The data wrangling process enables you to comply with the rules by cleaning and structuring data appropriately. 

Key Benefits of Data Wrangling

There are various benefits of the data wrangling process. You need to know these critical benefits and know what data wrangling is.

Enhanced Data Quality and Accuracy 

Data wrangling ensures quality and does not hinder the integrity of data analytics. Data accuracy is maintained throughout the process and enhances the reliability of insights derived from it. 

Raw data contains errors, inconsistencies, and missing values, hindering executive decision-making. Executives can make more informed decisions with better analysis and data-wrangled sets. 

Improved Analytical Efficiency

Data wrangling streamlines the data preparation process. It helps make more efficient data analysis by leveraging automation processes for routine tasks. With employed advanced data, organizations can allocate optimum resources at the preparatory stages and maximize the analytical efficiency at core tasks. 

This way, efficiency gains traction, and analysts explore more data and complex sets to frame better insights. 

Machine Learning and Advanced Analytics

Advanced analytics and machine learning models need clean and structured data for the effective functioning of their analysis. The data wrangling process transforms raw data into a readable format with machine learning models and analytical tools to facilitate sophisticated analysis. 

The predictive analytics, consumer segmentation, and trend analysis processes can shape the application of refined data into more accurate situations. 

Integration from Multiple Sources 

Today, sources are available in abundant form. Data is available from IoT devices, social media, enterprise systems, web networks, etc. The data wrangling process helps businesses integrate data from various sources and transform them into standardized formats to resolve discrepancies in the organization. The created cohesive dataset allows executives to make informed decisions with a more holistic view. 

What Steps Does the Data Wrangling Process Involve?

Now that we know what is data wrangling, we should understand what steps it involves. The crucial steps intend to transform the raw data into a format ready for analysis. Data transformation is essential for digging meaningful insights and influencing the decision-making and strategic planning process of business. 

With better data wrangling tools, data wrangling becomes a lot easier. Let’s check the steps involved in data wrangling. 



The first step of the data wrangling process is collecting data from various sources. These sources include files, external APIs, databases, or web scraping. Collecting data involves identifying sources, assessing their quality, and figuring out how to structure them. 

The primary goal of the discovery process is to build a good foundation for data preparation by recognizing its potential threats and opportunities. 


Once you collect data, you can organize the raw data into a readable format. You can organize the data in various formats like structured (SQL databases), semi-structured (JSON, XML files), or unstructured (text, images, or documents). 

Structuring needs to be in a more analysis-friendly format so that executives can quickly gain insights. Structuring data includes reshaping data and handling missing values. This way, data can be presented in a more standardized format, and the scope of manipulation is minimized. 

Some essential structuring elements are parsing data into structured fields, normalizing its consistency, and transforming data from text to lowercase for analysis. 


The cleaning process involves removing errors, inconsistencies, and duplication. This eliminates the possibility of skew analysis, resulting in better-prepared data sets. Removing irrelevant data and correcting mistakes contributes to the cleaning process. Dealing with missing values helps remove and estimate statistical methods, too. 

Cleaning is a crucial process that addresses the anomalies and impacts data reliability. Cleaning data ensures data accuracy and reliability through the downstream process.  


Enriching data involves enhancing data with some additional inputs that give context and depth. This may include merging datasets, extracting errors, and incorporating national data sources. 

The goal is to increase the original dataset and make it more comprehensive with valuable points. If you add data, make it structured and clean them first. 


Validating data ensures the reliability of processed data is on point. It checks the inconsistencies, verifies data integrity, and confirms the data adherence to set standards. Furthermore, validation helps build your confidence and establish the dataset’s accuracy. Validating ensures that data accuracy and quality are not compromised. 

It retains data integrity and ensures foreign keys match in a database. It also follows a quality assurance test that meets the predefined standards and rules of the validating process.  


Once the validation process is done, a more curated and validated dataset is produced for analysis. The dissemination and documentation of data are made for executives to glance at and gain insights from it. The final wrangled data is then stored in a data repository like a data warehouse to make it accessible for reporting and analysis. 

The storage is secure, and the queries and analysis parts are organized. After that, it is converted into a readable format. For publishing data, documentation is prepared with a detailed outlook of how data was refined, transformed, and audited.
