Have you ever woken up to find page break lines strewn across your carefully formatted Excel sheets? This frustrating occurrence can disrupt your financial models, especially when you’ve meticulously set print areas and aligned sections. While it may feel random and perplexing, this issue often stems from Excel's automatic adjustments in response to changes in data, formatting, or printer settings. Understanding the underlying causes can help you regain control over your spreadsheets and maintain the clarity you need for effective data management.
