Master Excel Formula Auditing: Show Formulas, Trace Dependents, and Use Turbo Trace for Better Accuracy
When it comes to working with spreadsheets, few tools are as powerful or as overwhelming as Microsoft Excel. From financial models to large data reports, formulas sit at the heart of every calculation, but auditing them can quickly become a challenge.
In this 2025 updated guide, we’ll walk you through how to show formulas in Excel, explain the role of trace dependents and precedents, break down the limitations of Excel’s native features, and introduce Turbo Trace the free add-in that makes auditing faster, easier, and far more accurate. To dive deeper into each step, Read more below.
Every Excel spreadsheet tells a story through formulas. But when a model contains dozens or even thousands of interlinked formulas, that story becomes difficult to follow.
Common challenges include:
Incorrect Results: Numbers don’t match expectations, but the source of the error isn’t clear.
Nested Functions: Formulas with multiple IFs, VLOOKUPs, or INDEX/MATCH combinations are hard to untangle.
Cross-Sheet Dependencies: Data linked across tabs or workbooks makes tracing errors time-consuming.
Collaboration Issues: When working on shared spreadsheets, understanding another person’s formulas can feel impossible.
Formula auditing is the process of decoding, tracing, and verifying formulas to ensure accuracy, efficiency, and reliability in your spreadsheet.
How to Show Formulas in Excel (Built-In Method)
Excel has a built-in Show Formulas option that lets you toggle between results and underlying formulas. Here’s how to use it:
Step 1: Open the Formulas Tab
Navigate to the Formulas tab in Excel’s ribbon menu.
Step 2: Click “Show Formulas”
Press the Show Formulas button. Instantly, every cell in your sheet will display the actual formula instead of the result.
Step 3: Toggle Back
Click the button again (or press Ctrl + ~) to return to normal view, showing results instead of formulas.
When is this useful?
Quickly scanning an entire sheet for formulas.
Spotting accidental hard-coded numbers.
Identifying missing references.
Using Trace Dependents and Trace Precedents in Excel
Beyond simply showing formulas, Excel provides two additional auditing tools:
Trace Precedents → Shows which cells feed into the selected formula.
Trace Dependents → Shows which cells rely on the selected formula.
These tools are helpful for visualizing relationships within a sheet. For example:
If you select a formula in cell D5 and click Trace Precedents, Excel draws arrows to the input cells that contribute to D5.
If you select the same cell and click Trace Dependents, Excel highlights the cells that depend on D5 for their calculations.
Limitation: These arrows work well within a single sheet but quickly become overwhelming with complex models or cross-sheet references.
Limitations of Excel’s Built-In Auditing Tools
While Excel’s Show Formulas, Trace Dependents, and Trace Precedents are helpful, they have critical limitations:
No Step-by-Step Breakdown: Excel shows raw formulas without explaining each function or operator.
Poor Cross-Sheet Tracing: Dependencies across sheets or workbooks are difficult to follow.
Manual Debugging: Errors in nested formulas require you to manually pick apart each layer.
Limited Error Detection: Excel won’t highlight inefficiencies or hidden risks in formulas.
For small spreadsheets, these limitations may not matter. But for financial models, dashboards, or enterprise datasets, you need something more powerful.
