Frequently Asked Questions About Online Calculators
Does it compare formulas?
It compares the values exposed by the workbook parser, including stored formula text where available. It does not recalculate Excel formulas.
Are files uploaded?
No. The XLSX files are parsed in your browser and are not sent to this site.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Worksheet cell difference report.
What should I check before using the result?
Open the Worksheet cell difference report in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Before downloading the result
Compare the Worksheet cell difference report with the original while both are fresh; destinations differ, and a quick check here saves a re-upload later.
