Dynamic Method to Reference Displayed Values Instead of Formula Values in Excel: Combined Application of CELL and TEXT Functions
This paper delves into a common yet often overlooked issue in Microsoft Excel: when a cell contains a formula and is formatted to display a specific number of decimal places, other formulas referencing that cell default to using the original formula value rather than the displayed value, leading to calculation discrepancies. Using Excel 2010/2013 as an example, the article introduces the core problem through a concrete case (e.g., C1=A1/B1 displayed as 1.71, but E1=C1*D1 yields 8.57 instead of the expected 8.55). Primarily based on the best answer, it provides a detailed analysis of the solution using the CELL function to retrieve cell format information, combined with the TEXT function to dynamically extract displayed values: =D1*TEXT(C1,"#."&REPT(0,RIGHT(CELL("format",C1),1))). The paper systematically explains the principles, implementation steps, and pros and cons (e.g., requiring recalculation after format changes) of this method, compares it with alternatives (such as the ROUND function or limitations of CELL("contents")), and extends the discussion to practical applications and considerations, offering a comprehensive and actionable reference for advanced Excel users.
