macOS still does not have a great native app for opening and editing tabular data files. Grid+ fills that gap: a lightweight desktop app that opens your files instantly, keeps scrolling smooth on large datasets, and stays out of your way.

Everything runs on your Mac. Your files never leave your machine.

Opening after download

Grid+ is not signed with an Apple Developer certificate yet. When you download the app from the web, macOS may block the first launch and show a security warning.

Option 1 — Right-click (recommended)

1. Open the DMG and drag Grid+ to Applications
2. In Applications, right-click Grid+ and choose Open
3. Click Open in the dialog

After that, you can open Grid+ normally with a double-click.

Option 2 — Privacy & Security

1. Try to open Grid+ once (macOS will block it)
2. Open System Settings → Privacy & Security
3. Scroll down to Security
4. If you see Grid+ was blocked, click Open Anyway

Option 3 — Terminal

xattr -cr "/Applications/Grid+.app"

Then open Grid+ from Applications as usual.
