Do you know what’s feeding your model?

We’ve all chased values across dozens of sheets only to lose track of where the number originally came from.
With PerfectXL Source Inspector, you can instantly trace any cell back to all its sources, whether they’re in the same workbook or linked from external files. See every step clearly visualized so you always know exactly where your data starts.

Complex workbooks often combine inputs from many sheets or even other Excel files. Source Inspector automatically maps these relationships and separates internal and external connections, giving you a transparent view of how data flows between sheets, tables, and workbooks.

Need to know which other files your model depends on? The tool lists every external link and connection, showing exactly which file, sheet, and range each value comes from. Quickly verify data sources and spot missing or outdated references before they cause errors.

Broken links and outdated references can quietly corrupt results. Source Inspector helps you identify them immediately, showing which formulas point to missing files or outdated data connections. This makes fixing data integrity issues faster and far more reliable.

When working with shared or inherited models, it’s hard to tell if all inputs are correct or consistent. Use the visual dependency map to confirm that each value comes from the right place and that no unexpected sources feed into your calculations.

Sometimes, two ranges look identical but aren’t, perhaps one pulls live data and another is hard-coded. Source Inspector lets you quickly compare data sources and highlight differences in how each range is populated, so you can detect weak spots or inconsistencies at a glance.

Need to prove where your results come from? Export your full source analysis into a structured Excel report. The report lists all internal and external sources, including their locations, values, and formulas, perfect for audits, version tracking, and quality control.

Explaining a model’s data flow can be tricky. With Source Inspector’s visual dependency map and source overview, you can easily show colleagues or auditors how each value is built up, from raw data to final result, making complex workbooks clear and understandable for everyone.
