10 Ways to Create Consistent Data in Microsoft Excel

Jun 13, 2024 | Excel Hints and Tips

Excel is a versatile tool that empowers users to manage and analyse data efficiently. Maintaining consistent data is crucial for accurate reporting, decision-making, and collaboration. In this blog post, we’ll explore ten strategies to ensure data consistency within your Excel spreadsheets.

1. Provide Clear Guidelines

Establish clear guidelines for data entry. For example, should United Kingdom be United Kingdom or UK? Pick one rule and stick with it.

2. Clean Up Messy Data using Functions

TRIM, CLEAN and PROPER are just some of the functions that can help to clean inconsistent data.  TRIM will remove extra spaces, CLEAN removes unprintable characters and PROPER changes the case to a capital on the first letter.  Many other functions can be utilised too.

3. Use Excel Tables

Convert your data range into an Excel table. Tables automatically expand as you add new data, maintaining consistent formatting and formulas.

4. Conditional Formatting

Highlight discrepancies using conditional formatting rules. By applying a format the data that does not obey these rules stands out and can be double-checked.

5. Consistent Column Headers

Give your columns clear, descriptive names and avoid abbreviations.  Make sure anyone who looks at the spreadsheet immediately knows what the data is. Even using consistent capitalisation and spacing in the headings can make it easier to read.

6. Data Validation Rules

Use Data Validation to limit data in cells to specific number ranges, date ranges or restrict text length. Even limit options to those in a preset list. By providing helpful error messages it will be easier for those entering the data to find out what is wrong and change it helping consistency.

Be aware that not all incorrect data will be caught by this for example if numbers are required between 1 and 100 and someone types 34 but meant 43 this would not be found.

7. Protect Your Worksheets

By protecting the whole sheet or specific parts of the sheet accidental changes of the wrong cells can be avoided. This includes formulas being overtyped leading to inconsistent calculations being performed in those columns. This error is often quite difficult to find.

8. Document Data Transformation Steps

If others are using the spreadsheet or you need a guide for yourself use a separate worksheet within the file to explain the steps to carry out the cleaning and transformation of the data.  This ensures that everyone working on this spreadsheet follows the same robust steps every time.

9. Utilise Autocomplete

Autocomplete automatically suggests the entry you are trying to input when entering data at the bottom of a table. Once a unique combination of letters has been typed a suggestion of the entry already in that column will be given and to accept it you just move out of the cell. Continuing to type something else overwrites this feature. By keeping an eye out for this happening you are less likely to end up with multiple mis-spellings of the same word in a column.

10. Regular Data Audits

Schedule regular checks of your data. Filters and pivot tables can often highlight multiple spellings of the same word giving you the opportunity to amend the underlying data. Validation can also be applied retrospectively to data already entered looking for data that is outside the expected parameters.

In conclusion, consistent data in Excel is vital for reliable analysis and informed decision-making. By implementing these ten strategies, you’ll create a robust dataset. Remember: a well-organised spreadsheet is a powerful tool to help you understand your data.
