Questions
Which files can it open?
Excel workbooks (.xlsx, any sheet), CSV and TSV. For a Numbers file, choose File › Export To › Excel… in Numbers first; save older.xls files as.xlsx.
What is a key column?
A column that names each row once, such as an order number, SKU or email. Sheetdiff suggests one; choose Row order when there is none.
What’s free, and what does a key add?
Everything is unlocked for 14 days. Then, without a key, Sheetdiff still compares files of any size with full counts and lists the first 500 differences. A key lists every difference and adds the Excel and HTML reports, on up to 3 Macs. It’s a one-time purchase on Gumroad, with no subscription.
Where do I enter my license key?
Choose Sheetdiff › Settings…, open the Pro tab, paste the key from your Gumroad receipt and click Activate.
How do I get updates?
Sheetdiff checks for updates on its own; you can also choose Check for Updates… from the Sheetdiff menu. Updates are free.
Do I have to pay again on another Mac?
No. One license key works on up to 3 of your Macs. Download the app again from your Gumroad receipt or library and enter the same key.

Privacy
Sheetdiff reads your spreadsheets on your Mac and never uploads them; it has no account or tracking. Your license key is kept in your Keychain. The only internet requests are the license check with Gumroad (when you enter a key and about once a week) and checking for updates at fitztoppicks.com.
