QuickEdit

UltraEdit is a text and code editor built for work that general-purpose editors often struggle with: large files, complex data manipulation, and security-sensitive workflows. It has been in the market for more than 30 years, is used by over 4 million users worldwide, and is trusted by enterprise customers across the Fortune 100, 500, and 1000. Individual users choose UltraEdit when everyday editors start to hit their limits. Common use cases include working with very large files, running advanced search and replace, using column and block editing, and handling more complex text and data manipulation. Organizations choose UltraEdit when they need a more secure and supportable editor behind sensitive workflows. That includes teams in banking, insurance, healthcare, government, and other regulated or risk-sensitive environments where unsupported tools can create too much uncertainty.

CotEditor is exactly made for macOS. It looks and behaves just as macOS applications should. CotEditor launches so quick that you can write your text immediately when you want to. CotEditor is developed as an open-source project that allows anyone to contribute. Colorize more than 50 pre-installed major languages like HTML, PHP, Python, Ruby or Markdown. You can also create your own settings. Split a window into multiple panes to see different parts of your document at the same time. Inspect Unicode character data of each selected character in your document and display them in a popover. There are no complex configuration files that require geek knowledge. You can access all your settings including syntax definitions and themes from a standard preferences window. You don't need to lose your unsaved data anymore. CotEditor backups your documents automatically while editing. Check and list-up the characters in your document that cannot convert into the desired encoding.
