Data Wrangling 101: Definition And Process

If your business uses the internet to collect a lot of data, you will need to perform data wrangling once you have the raw data you require. We list the process necessary for effective data wrangling below. Following data harvesting is the crucial process of data wrangling, also referred to as data munging. Here are some frequently asked questions about data wrangling, including definitions, applications, and best practices.

What is Data Wrangling?

Data wrangling, also referred to as data cleaning, is the process of transforming raw data into a format that can be used. This includes purging redundant data, fixing mistakes, and formatting data for straightforward analysis.

The process of data wrangling is crucial to data analysis. It’s challenging to make wise decisions or draw reliable conclusions from data without clean and organized data.

Why is Data Wrangling Important?

Data wrangling is crucial for a number of reasons. First, it is simpler to analyze data that is organized and clean. It is simpler to identify patterns and trends when data is formatted consistently.

Second, accurate data can aid in avoiding mistakes and errors. Poorly formatted or inaccurate data can result in erroneous inferences or decisions.

Data wrangling can also help you save time and money. Data that has already been organized and cleaned up makes it simpler to analyze and use for decision-making.

Who Should Do Data Wrangling?

Data wrangling can be a laborious and difficult process. Data analysis skills and familiarity with programming languages like Python or R are prerequisites. Data analysts and data scientists frequently handle data wrangling because of this.

But anyone who deals with data should be familiar with data wrangling. Business analysts, marketers, and even executives who must make data-driven decisions are included in this.

The Data Wrangling Process

The data wrangling process typically involves several steps:

1. Data Collection

The first step in the data wrangling process is data collection. This involves gathering raw data from various sources such as databases, spreadsheets, or APIs.

2. Data Cleaning

The next step is data cleaning. This involves removing duplicate data, correcting errors, and formatting data so that it can be easily analyzed.

3. Data Transformation

After the data is cleaned, it may need to be transformed or reshaped to make it easier to analyze. This can involve tasks such as merging data from different sources, splitting columns, or converting data types.

4. Data Enrichment

Data enrichment involves adding additional data to the existing dataset. This can include things like demographic data or customer behavior data.

5. Data Analysis

Once the data is cleaned and organized, it can be analyzed using various data analysis techniques such as regression analysis or data visualization.


The process of data wrangling is crucial to data analysis. It entails preparing raw data for use by cleaning, transforming, and organizing it. Data that has been cleaned up and organized makes analysis simpler, can help prevent errors, and can save time and resources. Anyone who works with data should be familiar with the process, even though data analysts and data scientists tend to handle data wrangling more frequently.
