A simple CSV editor for macOS.
About this fork: This is a maintained fork of the original jakob/TableTool, updated to run on current macOS versions and Apple Silicon. Releases are built as universal binaries (Apple Silicon + Intel) and require macOS 11 or later.
CSV is a widely used file format for storing and exchanging tabular data, and almost every spreadsheet and database app (e.g. Excel and Numbers) supports it. Unfortunately, not all CSV files are made equal: they differ in record delimiters (comma or semicolon), character encodings, decimal separators and quoting styles.
Table Tool handles these issues automatically. It detects the format of a CSV file for you and displays its contents in a table view, making it the easy way to create, edit and convert CSV files.
- Open files: Table Tool detects the format specifications of a CSV file (record delimiter, character encoding, etc.) automatically. You can also set them manually.
- Edit files: Edit cells, rows and columns in a grid-based interface, with full undo/redo support.
- Convert files: Convert an existing CSV file to a different format.
Download the ZIP from the
latest release,
unzip it and move Table Tool.app to your Applications folder.
Release builds are ad hoc signed and not notarized, so macOS will warn you the first time you open the app. To approve it, try to open the app once, then go to System Settings → Privacy & Security and click Open Anyway.
The upstream project has been dormant for a while and its last release predates Apple Silicon. This fork:
- Modernizes the Xcode project for current macOS SDKs and Apple Silicon, building a universal binary with a macOS 11.0 deployment target
- Replaces deprecated AppKit/Foundation API usage and migrates document types to UTI-based declarations
- Adds GitHub Actions CI and an automated release workflow that builds, tests and publishes tagged versions (see RELEASING.md)
No features have been added or removed beyond keeping the app working — the goal is simply a CSV editor that runs on today's Macs.
Requires a recent Xcode. Clone the repository, open
Table Tool.xcodeproj and build the Table Tool scheme, or from the command
line:
xcodebuild -project "Table Tool.xcodeproj" -scheme "Table Tool" buildTable Tool seeks to be a great and simple CSV file editor and nothing more. Formatting options or features like formulas are out of scope. If something is broken or missing, please open an issue — well-documented issues and pull requests are what move this project forward.
Table Tool was made by Sandro Peham, Andreas Aigner and Jakob Egger.
