2-Day Excel Data Cleansing And
Building Techniques Course In
Singapore (New Exclusive Launch)

It is vital to keep your data clean to build quality data analytics and drive better decision-making

Excel Data Cleansing And Building Techniques Course Overview

Dealing with Big Data and Data Analysis? Make sure your data is clean.

What is Data Cleansing or Data Cleaning? It is a process that involves detecting and correcting or removing corrupt, inaccurate, incomplete and irrelevant records from a record set, table or database.

Do you face the following challenges with your data?

  • Extra space(s) in the front, back or even within the data
  • All data are in upper case or in lower case
  • Position of the columns are not correct
  • Lots of holes (empty cells) in the data
  • Extra labels within the data list
  • Merged cells within the data list
  • Non-printable characters within the data
  • Data are stored in horizontal format (standard is vertical)
  • Date field become text field (cannot be calculated)
  • Person names are stored in one field instead of splitting into First and Last name
  • Duplicate records, etc

Apart from the above, there are many more challenges people face daily with their data sets. Regardless of the reporting tools you use to generate the unclean data (e.g. Power BI, Tableau, Power Pivot or Pivot Table), the generated reports will come out to be inaccurate.

Data cleaning is not just recommended, but a required process. Data is the core business asset that needs essential management for every business enterprise to generate returns. Data cleaning plays a pivotal role during decision-making process or data analysis. Incorrect or inconsistent data leads to poor business decisions and inferior customer relationship management. It can land your business in big trouble!

Data sets have the potential to grow inaccurate over time in many ways, from human error, inconsistent data styling to aging information. It is vital to keep your data in a uniform state with regular data cleaning for building quality data analytics and business intelligence solutions. This will improve the decision-making process, streamline business practices and help you efficiently use your time well.

In today’s business world, incorrect or inconsistent data can be costly. When the data is clean, not only does it provide substantial growth to the business, it also helps to maximise employees’ efficiency and improve their response rates.

False conclusions are derived from incorrect or inconsistent data. Your ability to clean the data highly impacts the quality of results. The longer you allow your Excel spreadsheet to run without proper excel data cleaning, the longer it will take to clean them up.

This Excel Data Cleansing and Building Techniques course, developed by Alaster, is conducted exclusively in Advanced Learning Singapore. You will be guided on the process of preparing data for accuracy and to build data not found in the existing data before using it as an analytics input. It involves the following:

  • Analysing the data to detect any problems for reporting
  • Clean the data if problems are detected: remove incorrect data, update incomplete information, clear or reformat the improper formatting, remove extra spaces and many more
  • Reorganizing and shaping the data
  • Building data that not found in the existing data
