Please include the app name and version, your device and its system version, and what you expected to happen. Please do not send files with personal or confidential data; a small sample with made-up values is enough.

Restore purchases

If you bought Pro and the app shows Free (for example after reinstalling), open Settings (or the Pro sheet) in the app and choose Restore purchases; the result is shown there. On a Mac you can also choose File › Restore Purchases: it opens Settings › Subscription & Purchases (or uses the Pro sheet if it is open) and shows the result there. Use the same Apple ID you bought with.

Manage or cancel a subscription

Subscriptions are managed by Apple, not in the app. On iPhone or iPad: Settings, your name, Subscriptions. On a Mac: the App Store app, your account, Subscriptions. Apple’s instructions: Apple Support: cancel a subscription.

Refunds are requested from Apple: reportaproblem.apple.com. Subscriptions and Purchases

Free and Pro

Free exports up to 200 rows per output table. Pro removes that limit. Everything else works the same in Free.

System requirements

Mac: macOS 13 or later
iPhone: iOS 16 or later
iPad: iPadOS 16 or later

Supported files

Excel (.xlsx, .xls) and text tables (.csv, .tsv, .txt).

Known limitations

Only the first worksheet of an Excel workbook is read.
An Excel output file holds at most 1,048,575 data rows (the Excel sheet limit). Use CSV for larger results.
CSV text is read as UTF-8 when it is valid UTF-8; otherwise the app guesses Big5, GB18030 or Windows-1252 and tells you it is a guess.
Very large files are limited by your device’s memory.
The app is available in English and Traditional Chinese.
Keys are compared as text. You can choose to ignore spaces at the start and end of keys and upper/lower case; there is no fuzzy or approximate matching.
The main table and the lookup table are one file each.
When a key appears more than once in the lookup table, the first matching row is used and the repeated keys are listed so you can check them.
