Data Wrangling is turning out to be a key component of the marketing industry. Statistics say that U.S. revenue on “data processing and related services” will amount to 1,978 billion dollars by 2024. The internet produces millions of data every passing second. Proper usage of these data could highly benefit business people with quality insight. Not all raw data is eligible to undergo the data analysis process. They must undergo some preprocessing steps to meet up desirable formats. This article will let you explore more about one such process called “Data Wrangling.”
Data Wrangling is the process of transforming raw data into standard formats and making it eligible to undergo the analysis process. This Data Wrangling process is also known as the Data Munging process. Usually, the data scientists will come face with data from multiple data sources. Structuring raw data into a usable format is the first requirement before subjecting them to the analysis phase.
Data Munging, or the Data Wrangling process, simplifies the job tasks of the data scientists in various ways. Here are some of those benefits.
Data analysts may find it easy to work on wrangled data as they are already in the structured format. This will improve the quality and authenticity of the results as the input data are free from errors and noise.
Some unusable data that stays for so long turns into data swamps. The Data Wrangling process makes sure all incoming data is turned into usable formats so that they don’t remain unused in data swamps. This increases the data usability to multiple folds.
Data Wrangling can help the users handle null values and messy data by mapping data from other databases. So the users are risk-free as they are provided with proper data that can help in deriving valuable insights.
Data professionals do not have to spend much time dealing with the cleaning and mining process. Data Wrangling supports business users by providing them with suitable data that is ready for analysis.
Gathering data from multiple sources and integrating them will give business analysts a clear understanding of their target audience. This will let them know where their service works and what the customer demands. With these exact methods, even non-data professionals can find it easy to have a clear idea of their target.
Both Data Wrangling and Data Mining work to build valuable business insight from raw data. But, they vary with a few of their functionalities as follows.

The Data Wrangling steps comprise 6 necessary and sequential data flow processes. These steps break down the more complex data and map them to a suitable data format.
Data discovery is the initial step of the Data Wrangling process. In this step, the data team will understand the data and figure out the suitable approach to handle them. This is the planning stage of other phases. With a proper understanding of the data, data scientists will decide the order of execution, operations to perform, and other necessary processes to enhance data quality.
Example: A data analyst prefers analyzing the visitor counts of a website. In this process, they will go through the visitor’s database and check if there are any missing values or errors to make decisions on the execution model.
The unruly data collected from various sources will not have any proper structure. The unstructured data are memory-consuming which will eventually reduce the processing speed. The unstructured data may be data like images, videos, or magnetic code. This structuring phase parses all the data.
Example: The ‘website visitors’ data contains user details, like username, IP address, visitor count, and profile image. In this case, the structuring phase will map the IP addresses with the right location and convert the profile image into the required format.
Data Cleaning works to improve the quality of the data. The raw data may contain errors or bad data that can bring down the quality of the data analysis. Filling null values with zeros or suitable values mapped from another database. Cleaning also involves removing bad data and fixing errors or typos.
Example: The ‘website visitors’ dataset can have some outliers. Consider there is a column that denotes the ‘number of visits from unique users. The data cleaning phase can cluster the values of this column and find the outlier that varies abnormally from other data. With this, marketers can handle outliers and clean the data.
This enriching step takes your Data Wrangling process to the next stage. Data Enriching is the process of enhancing the quality by adding other relevant data to the existing data.
Once the data passed the structuring and cleaning phases, enriching the data comes into the picture. Data scientists decide if the need requires any additional input that could help users in the data analysis process.
Example: The ‘website visitors’ database will have visitors’ data. Data scientists may feel some excess input on ‘website performance’ can help the analysis process they will include them as well. Now the visitor count and performance rate will help the analysts to find when and where their plans work.
Data validation helps users evaluate the data consistency, reliability, security, and quality. This validation process is based on various constraints that are executed through programming codes to ensure the correctness of the processed data.
Example: If the data scientists are collecting information on the visitor’s IP address, they can come up with constraints to decide what kind of values are eligible for this category. That is, the IP address column cannot have string values.
Once the data is ready for analytics, the users will organize the wrangled data in a database or datasets. This publishing stage is responsible for delivering quality data to the analysts. The analysis-ready data will then be subject to an analysis and prediction process to build quality business insights.
Data Streamlining – This Data Wrangling tool continuously cleans and structures incoming raw data. This helps the data analysis process by providing them with current data in a standardized format.
Customer Data Analysis – As Data Wrangling tools collect data from varied sources, they get to know about users and their characteristics with the data collected. Data professionals use Data Science technologies to create a brief study on customer behavior analysis with this wrangled data.
Finance – Finance people will analyze the previous data for developing financial insight for plans. In this case, Data Wrangling helps them with visual data from multiple sources that are readily cleaned and wrangled for analysis.
Unified View of Data – The Data Wrangling process works on the raw data and complex data sets and structures them to create a unified view. This process is responsible for Data Cleaning and Data Mining process through which they improve data usability. This brings together all the raw data usable together into a single table or report making it easy for analysis and visualization.
Proxies supports data management and data analysis with its unique features. While collecting data from multiple sources, users may encounter many possible restrictions, like IP blocks, or geo-restrictions. Proxyscrape furnishes proxies that are capable of bypassing those blocks.
Data Wrangling is the process of unifying and transforming messy data, raw data usable, and other unstructured data into the desired format. Unruly data is subjected to data transformations, like data cleaning, data mining, and data structuring processes to convert them into a standardized format. This eases the data flow while analyzing the data.
The Data Wrangling process has a sequential order of execution like discovery, structuring, cleaning, enriching, validating, and publishing.
Proxies play a major role in the wrangling of data. The proxy makes use of their anonymity and scraping features to collect data from multiple data sources without revealing their own identity. This hides the user’s IP address and lets them collect data with the proxy address.
Both the techniques focus on improving data quality, but they differ in functionality. Data Wrangling focuses on collecting and structuring raw data into other suitable formats that help the data analysis process. Whereas, the Data Mining process is intended to find the pattern or relationship among the data.
There are enough Data Wrangling tools available in the market to simplify and automate the process.
Apart from the need of programming languages like Python and their libraries, visual data wrangling tools like Tableau will also help data wrangling process.
Data wrangling might sound new to most of the general audience. Data wrangling is a subset of data mining techniques you may use to qualify the raw data for analytical purposes. Proper sequential execution of the mentioned steps will simplify the complexity of data analysis. You can take support from Data Wrangling tools or solutions to automate the process. Proxyscrape, with its anonymity proxies, will ease the Data Wrangling system.
