Find duplicate rows, spot odd numbers, reconcile two tables - offline, on your own PC.
Import csv or xlsx, export a clean Excel file. Your original file is never touched.
Try before you buy: 3 days / 10 runs free, every feature unlocked.
Not another Excel add-in. One small program you double-click.
The same customer ordered twice, the same record typed in twice, the same name three times in a list. Pick the file, click Start, and duplicates come back grouped - with how similar they actually are.
A quantity of 99999, an extra zero on an amount, an impossible date. You do not have to teach it what "odd" means: it measures the normal range of your own data first, then judges against that.
Most tools make you guess a threshold, and when you guess wrong they say "no duplicates found". FlySense measures the background similarity of your table, sets the threshold from your chosen strictness, and prints the numbers so you can see what it did.
Everything runs inside your own PC. Unplug the network cable and it still works. Customer lists, payroll and bank data never leave the machine - which matters if you handle other people's money.
Your source file is opened read-only and never modified. Results are exported to a fresh Excel file you can send straight to your manager.
Unzip and double-click. No installation, no registry changes, no background service. Easy to explain to your IT department.
One program, two license keys. Start with Personal and upgrade later by paying only the difference.

No. It is a one-time payment. Version 1.x will not ask you for more money; a future major version would be announced separately, with a discount for existing customers.

No - once a license key has been issued the sale is final, because a key is a one-off digital item. That is exactly why there is a free trial with every feature unlocked: please run it on your own file first. See the refund policy for the few cases where we do refund.
