Frequently asked questions
How do I find duplicates in Excel?
In Excel you need conditional formatting or a formula per column. With ARIA you upload the file: it counts the rows and the distinct values of the key column, and shows what appears twice.
Does ARIA delete duplicates from my file?
No. ARIA never changes your file: it shows you the duplicates, and you decide.
Does my data stay private?
Your Excel files are deleted after 24 hours and are never used to train a model.
Is it free?
