What Is Data Cleaning? How To Clean Data In 6 Steps?

Data cleaning is the backbone of healthy data analysis. When it comes to data, most people believe that the quality of your insights and analysis is only as good as the quality of your data. Garbage data equals garbage analysis out in this case.

If you want to establish a culture around good data decision-making, one of the most crucial phases is data cleaning, also known as data scrubbing.

What is data cleaning, cleansing, and scrubbing?

Clean data is crucial for practical analysis. The first stage in data preparation is data cleansing, cleaning, or scrubbing. It’s the process of analyzing, recognizing, and correcting disorganized, raw data.
Data cleaning entails replacing missing values, detecting and correcting mistakes, and determining whether all data is in the correct rows and columns. A thorough data cleansing procedure is required when looking at organizational data to make strategic decisions.

Clean data is vital for data analysis. Data cleaning sets the foundation for successful, accurate, and efficient data analysis. Because the information in the dataset will be disorganized and scattered without first cleaning it, the analysis process won’t be clear or as precise. Clean data is required for effective analysis; it’s as simple as that.

Data cleaning aims to produce standard and uniform data sets that allow business intelligence and data analytics tools to access and find the relevant data for each query.

What are the benefits of data cleaning? 

Data cleaning is beneficial to your career as a data specialist. Data cleaning helps other businesses, making your position as a data professional easier.

The longer you store insufficient data, the more it will cost your firm in both money and time. This also applies to quantitative (structured) and qualitative (unstructured) data.

It’s the 1-10-100 principle:

It is better to invest $1 in prevention than spend $10 on correction or $100 on fixing a problem after failure.

These are just a few of how it will assist you in your job:


Clean data allows you to conduct your study faster. Because having clean data avoids the creation of numerous mistakes, and your findings will be more accurate, you won’t have to repeat the entire operation because of incorrect results.

Error Margin

Even if you are highly eager for outcomes, the results will not be accurate if the data isn’t clean. As a result, the result may or may not be accurate when you present your work. As a consequence of adopting this practice, you must become accustomed to slowing down and correcting data before presenting it. There’s less room for errors as a result of this.


You’ll soon learn to be more exact with the data you put in at first since data cleaning takes up so much time. Data cleaning will still be required for various reasons, but doing it helps you get used to be more precise from the start.

Data cleaning challenges

Analysts may have difficulties with the data cleaning process since good analysis requires ample data cleaning. Organizations frequently lack the attention and resources to affect the study’s conclusion due to a lack of data scrubbing efficiency. Inadequate data cleansing and preparation are often a cause for inaccuracies slipping through the gaps.

The lack of data scrubbing, which allows for inaccuracies, is not the fault of the data analyst. It’s a symptom of a more significant problem: manual and siloed data cleaning and preparation. Traditional data cleansing and preparation also take too much time beyond the shoddy and faulty analysis.

Forrester Research claims that up to 80% of an analyst’s time is spent on data cleansing and preparation. So much time is spent cleaning data that it’s easy to overlook data cleaning processes. Most businesses require a data cleansing tool to help them analyze the data more efficiently while saving time and money on preparation.

The least enjoyable activity for data scientists is the cleaning and organizing their data, according to 57% of respondents.

Comparison: Data cleaning vs data transformation

Removing data that does not belong in your dataset is known as data cleaning. Data conversion from one form or structure to another is called data transformation.

Cleaning data is one of the most critical tasks for every business intelligence (BI) team. Data cleaning processes are sometimes known as data wrangling, data mongering, transforming, and mapping raw data from one form to another before storing it. This post focuses on the techniques of cleaning up your information.

How to clean data in 6 steps?

The first step in any data cleaning project is to take a step back and assess the overall picture. Consider, what are your objectives and expectations?

You’ll need to develop a data cleanup strategy next to reach those objectives. Focus on your top metrics is a fantastic starting point, but what questions should you ask?

  • What is the most important measurement you want to achieve?
  • What is your firm’s objective, and what do each of your employees hope to get out of it?

The first step is to gather the key stakeholders and get them to brainstorm.

Here are some best practices for developing a data cleaning procedure:

Monitor errors

Keep track of trends where most of your mistakes originate from. This will make it easier to spot and correct incorrect or faulty data. Records are particularly significant if you’re incorporating multiple solutions into your fleet management system so that other teams don’t get bogged down.

Standardize your process

Make sure that the point of entry is standardized to help minimize duplication.

Validate data accuracy

When you’ve finished cleaning your current database, double-check the consistency of your data. Invest in real-time data management technologies so that you may clean your data regularly. Some tools even employ artificial intelligence (AI) or machine learning to improve testing for accuracy.

Scrub for duplicate data

To help save time when examining data, look for duplicates. Repeated data can be avoided by researching and purchasing various data cleaning tools that may process raw data in bulk and automate the procedure.

Analyze your data

Use third-party sources to integrate it after cleaning, validating, and scrubbing your data for duplicates. Third-party suppliers can obtain information directly from first-party sites and then clean and combine the data to provide more thorough business intelligence and analytics insights.

Communicate with your team

Share the new procedure for cleaning your data with your team to help promote its use. It’s critical to keep your data clean now that you’ve cleaned it. Keeping your teammates informed will assist you in generating and strengthening customer segmentation while also sending more relevant information to consumers and prospects. 

Finally, check and review data regularly to discover any anomalies.

When you’re done with your data, make sure it’s clean. Whether you’re using simple numerical analysis or sophisticated machine learning on huge documents, open-ended survey responses, or consumer comments worldwide, cleaning up your data is crucial in any well-executed study.
