You build VLOOKUPs, INDEX-MATCHes, variance formulas. When columns change, everything breaks. When the file changes, you start over.
A $50,000 variance hidden in 500 rows. You don't see it scrolling. It ends up in your report.
Comparing budget vs. actual involves confidential financial data. Uploading it to a server is not an option.
Drop two files. Configure key columns and value columns. DataVariance calculates dollar and percentage variances, highlights the largest deviations, and generates an exportable report.
Both files are displayed side by side with differences highlighted.
Every row gets a dollar and percentage variance, sorted by impact.
The largest variances are summarized at the top for quick review.
Export the full report to Excel with formatting and variance highlighting.
