Which option describes good data practices in Excel?

• A. Clear headers, no merged cells, consistent formatting
• B. Merge cells for emphasis
• C. Random formatting
• D. Inconsistent headers

Answer: (A)

Good data practices in Excel start with a clean, well-structured sheet. Clear headers tell you exactly what each column represents, which is essential for accurate calculations, sorting, filtering, and using formulas. Merged cells often look neat but they break the data structure: they complicate sorting and analysis, and many tools struggle or fail when data isn’t in uniform columns and rows. Consistent formatting—same font, alignment, decimal places, and date formats—helps readability and ensures data types are interpreted correctly by Excel and any analysis you run. When you combine these elements—clear headers, no merged cells, and uniform formatting—you create data that is easy to manipulate and trustworthy. Other practices weaken data quality: merging cells for emphasis hides the true data layout and disrupts analysis; random formatting makes the sheet hard to read and increases the chance of errors; inconsistent headers create confusion about what each column contains, leading to misinterpretation and mistakes.
