Keeping Data Clean

Know how to remove duplicates from your data in Excel? It’s easy! Just check the ‘Keeping Data Clean’ section with sub-sections ‘Automating the Process’ and ‘Creating Rules to Avoid Duplicates.’ These will give you step-by-step instructions on how to clean up your data quickly and effectively.

Automating the Process

To streamline the process, Excel offers an automated feature for removing duplicates from your data. This feature can save a significant amount of time and effort while ensuring that your data is accurate and up-to-date.

Here’s a three-step guide to automating the process:

  1. Select the data range you want to work with.

Another aspect to keep in mind when automating this process is that if you have different formats in which data has been entered (such as “12/06/2021” vs. “June 12, 2021”), these items will not be treated as duplicates by Excel’s algorithm.

Prevent the dreaded déjà vu of duplicate data by setting up some sweet rules in Excel. No time-travel required.

Creating Rules to Avoid Duplicates

Creating Regulations to Prevent Data Reiteration in Excel

To maintain tidy and organized records, it is essential to avoid duplicate data entries in an Excel sheet. By setting up rules in Excel, it becomes effortless to prevent data from being entered twice unintentionally.

Below are the three steps to creating standards in Excel that can help stop reiteration of information:

  1. Select the databank column by clicking on its header.
  2. Under the “Home” tab, choose the “Conditional Formatting” option.
  3. Click on “Highlight Cells Rules” and then select “Duplicate Values.”

Although standardization can sustain uniformity, one should always be cautious when setting up rules to eradicate redundancies as unintended deletions may result.

When duplicates occur in a specific field and not across various columns, conditional formatting comes in handy. It helps highlight duplicate occurrences in a specific cell or column, making identification and deletion easier.

An associate’s template project contained multiple duplicates that resulted from incorrect referencing of charts. It led to errors during report generation and wasted time fact-checking data entries. He eventually managed a solution by spotting problem areas with conditional formatting.
