Mac App Store Microsoft Store What it does

See it in action

Open a CSV, filter it, clear it. Thirteen seconds, no cloud.

TKG CSV Viewer displaying a local CSV file in a native macOS table — On the Mac: a native SwiftUI table.

TKG CSV Viewer on Windows showing 50,000 rows of a sales CSV file — On Windows: 50,000 rows open in 48 ms.

A calm workspace for tabular data

Open local CSV files. Choose a file from Finder or File Explorer and inspect it in a fast table. On Windows, right-click a .csv file and choose Open with → TKG CSV Viewer.
Find what matters. Type a word and see only the rows that contain it, in any column.
Sort and page. Click a header to sort; numbers sort as numbers. Choose 50 to 1000 rows per page.
Export the result. Save the filtered, sorted rows as a new CSV file.

Private by design

Local processing

CSV contents are processed on your computer. There is no upload service, account, or vendor cloud dependency.

Focused product

No ads and no analytics SDK. The app is built to do one data task quickly and stay out of the way.

Mac and Windows

Both versions share the same Rust CSV core for fast parsing of large local files. The Mac version has a native SwiftUI interface; the Windows version is a lightweight desktop app with its own window, no runtime to install.
