Understanding Duplicates in Spreadsheets

What Are Duplicates? 🤔

Duplicates refer to identical or very similar entries that appear more than once in a dataset. They can significantly skew your analysis and may lead to incorrect decisions based on faulty data. Here are some key reasons why you should remove duplicates from your spreadsheet:

  • Data Integrity: Ensures that your data is accurate and reliable.
  • Efficiency: Reduces the file size and improves loading times.
  • Analysis Accuracy: Guarantees that any analytical models built on the data are valid.

Common Sources of Duplicates

  • Data Imports: When importing data from multiple sources, overlaps can occur.
  • Manual Entry: Users may inadvertently enter the same data multiple times.
  • Copy-Paste Errors: Copying data without proper checks may lead to duplicates.
