An open-source Mac CSV editor with automatic format detection and direct cell, row and column editing.
About TableTool
TableTool is an open-source CSV editor for macOS. It opens CSV files, detects their format settings automatically, and shows the contents in a table view. Users can edit cells, rows, and columns in a grid, or convert an existing CSV file to a different format.
The project is intentionally limited. Its stated scope is a simple CSV editor and nothing more, so formatting options and formulas are out of scope. The README describes it as a simple CSV editor for OS X and points to the Mac App Store for download.
Key features
- Automatically detects CSV record delimiter, character encoding, and quoting style
- Allows manual setting of CSV format specifications when needed
- Grid-based interface for editing cell contents
- Edit rows and columns directly within the table view
- Convert an existing CSV file to a different format
Best for: Mac users who need to open, edit, or convert CSV files from different sources without the features of a full spreadsheet application.
Good for
- Open source and distributed under the MIT License
- Handles differing CSV delimiters, encodings, and decimal separators automatically
- Focused on simple CSV editing
Watch out for
- Formatting options and formulas are explicitly out of the project's scope
- Described in its README as a CSV editor for OS X
