The world of data is deep, complex, and always expanding. It is easy to understand why having the right data in the first place can make all the differences in business. Business users depend on data and information to make just about every business decision.
Do you know what is data wrangling? No, then this blog is for you.
A good data wrangling will be able to interpret, clean, and transform data into valuable insights. If data is incomplete, unreliable, then analyses will be too-diminishing the value. Data wrangling seeks to remove that risk by ensuring data is in a reliable state before its analyzed.
In this blog, we’ll discuss what is data wrangling and its steps? I hope you will understand what is data wrangling easily.
Let’s begin!
what is Data wrangling
Table of Contents
Data wrangling is the process of cleaning, structuring, and enriching raw data into useful material. It can be a manual and automated process and practice of converting and then plotting data from one raw form into another.
Examples:
- Consolidate multiple data sources into a single dataset for analysis.
- Identifying gaps in data and either filling and deleting them.
Benefits of data wrangling
- Data wrangling helps to remove data usefulness as it converts data into an appropriate format for the end system.
- It helps to quickly build data flow within an in-built user interface and automate the data flow process.
- Integrates various types of information and their resources.
- Helps users to process very large volumes of data easily and easily share data flow techniques.
Importance of data wrangling
- Raw data: Making raw data work. Accurately wrangled data guarantees that quality data is entered into the downstream analysis.
- Location: Getting all data from various sources into a centralized location so it can be used.
- Cleansing: It is the process of detecting and correcting inaccurate records from a table. Cleansing the data from the noise or missing elements.
- Stage: Data wrangling acts as a preparation stage for data mining, which involves gathering and making sense of it.
- Piecing: Piecing is a term used to describe the act of assembling pieces by machine. Piecing together raw data according to the required format and understanding the business context of data.
Why is data wrangling necessary?
- Analytic-based table: It is used for machine learning. Each row in the table shows a unique entity with columns containing information about that organization for a specific point in time: it’s assigned and its relationship with other entities.
- De-normalized transactions: Transactional information is used for managerial business operations, such as an item in a particular order, including the complete order and detailed product information.
- Time-series: One or more attributes about a specific entity over time. For standard time series analysis, the observation must be divided into two consistent increases of time. Often the entity and its trend attributes are aggregated over time.
- Document library: A consistent corpus of documents, generally text, for analysis by text mining.
Steps in data wrangling
- Discovery: Discovery refers to a process of familiarizing yourself with data so you can actualize how you use it. Before cooking a meal, you can look in your kitchen to see what components you have at your disposal. It is an important step, as it will inform every activity that comes afterward.
- Structuring: Raw data is typically unpractical in its raw state because it’s either incomplete or misformatted for its studied application. It is the process of gaining raw data and changing it to be more readily controlled. Your data will depend on the logical model you use to interpret it.
- Cleaning: Cleaning is the process of removing inherent errors in data that might bend your analysis; it’s less valuable. Cleaning can come in many different forms, including deleting empty cells or rows, removing irregularity, and systematic inputs. Data cleaning aims to ensure there are no errors that could influence your final analysis.
- Enriching: You must determine whether you have all the data necessary for the project in hand. If not, you may choose to enrich your data by including values from other datasets. For this reason, it’s important to realize what other data is available for use.
- Validating: Data validating is the process of verifying that your data is both consisting and of a high enough quality. You may find issues you need to resolve during validation that your data is ready to be analyzed. It is typically achieved through various automated processes and requires programming.
- Publishing: Once your data has been confirmed, you can publish it. This involves making it available to others within your business for analysis. The format you use to share the information, such as a written report, will depend on your data.
Tools used for data wrangling
- Excel spreadsheet: This is the most basic structuring tool for data wrangling.
- Openrefine: a more professional computer program than excel.
- Tabula: Often referred to as the “all in one” data wrangling solution.
- CSV kit: For changing of figures.Its suite of command-line tools for converting to and working with CSV.
- Python: Numerical python comes with many functional features.
- Pandas: Pandas is designed for fast and easy data survey operations. It allows joining large sets of data with one python statement.
- Plotly: Mostly used for an interactive paragraph like line and scatter plots, etc.
Conclusion:
In this blog, we discussed what is data wrangling and the importance of data wrangling. I hope you have understood what is data wrangling. It is the process of converting raw data into such a form to become more successful, and it can help reduce the burden of the data analysis process. It helps find out the most relevant information and, after that, supports the data analysis process so that less time is consumed to bring out the most dependable outcomes.

Frequently asked questions(FAQs)
Do we need data wrangling?
Data wrangling is a necessary component of any business, and it is used to convert raw data into practical information. This essential plan has been done manually, but it doesn’t have to be this way.
Is data-wrangling part of data mining?
Data mining is the process of sifting and sorting through data to find patterns and hidden relationships in larger datasets. In contrast, data-wrangling requires a few steps, such as cleaning, enriching, etc.
