About Caxton

What is Caxton?

Caxton is a native Mac editor for text, CSV files, and structured data that opens files of any size directly from disk.

What Caxton does

The application edits large files using memory mapping, displays CSV files in an editable grid with column transforms and deduplication, provides log filtering by timestamp and severity, and performs regex search and batch replacements.

Who Caxton is for

Developers, analysts, and Mac users who work with large text files, CSV exports, and multi-gigabyte logs.

How Caxton works

Users open files directly from disk without imports, view contents as raw text or structured tables, apply column transforms or filters, and save changes back to the original file.
