It is a common occurrence for financial modelers to scroll through a model and encounter unused columns beyond the model's timeline in almost every worksheet. Hiding these extra columns after the end of the model timeline offers several key advantages that every financial modeler should be aware of:

• Prevents Unintended Data/Formula Extension: Reduces the risk of unwanted formulas or data being copied beyond the relevant timeline.
• Improves Visual Appeal: Keeps the workbook cleaner and more organized, enhancing its professional appearance.
• Streamlines Navigation: Makes scrolling through the financial model more efficient, helping users focus on relevant data.

Structured Format in the Model

Financial modelers often begin by creating a formula in the first cell of a timeline and then copying it across subsequent columns. However, when unused columns beyond the model timeline are not hidden, it becomes challenging to stop at the last relevant column. There is a risk that the formula might unintentionally extend to the last column of the worksheet.

While it may seem trivial for a regular user to manually delete formulas from these unintended columns, for professionals building financial models, this is not an efficient approach. A well-structured model should have a clear endpoint for the timeline, preventing errors and maintaining the integrity of the workbook.

Improving Worksheet Visibility

From a financial model audit perspective, particularly when presenting to senior management, the focus is often on high-level outputs such as dashboards or summary sheets. These stakeholders are primarily interested in key performance indicators (KPIs) and overall model outputs. By hiding unused columns, you can enhance the user experience by presenting a concise, streamlined view of the model. This makes it easier for stakeholders to quickly analyze the necessary data without excessive scrolling or searching for relevant information.

Hiding irrelevant columns ensures that the model provides a narrowed-down, focused view, allowing decision-makers to effectively engage with the data and conduct their analysis with minimal effort. This approach not only improves clarity but also contributes to a more professional and polished presentation of the financial model.

Conclusion

Hiding unused columns after the end of a model timeline is a simple but effective way to optimize your Excel models. It helps the modeller in avoiding any steps which may lead to increase in the file size and calculation speed. By adopting this best practice, financial modelers can ensure that their models remain efficient, user-friendly, and easy to maintain over time.
