Caxton is a native Mac editor for text and data files of any size: logs, CSVs, TSVs, JSON, SQL dumps and exports. Every delimited file opens as text and as a typed table, edits in either view show in the other, and saving writes the same file back. Nothing is imported or uploaded.
It memory maps files instead of loading them into RAM. A 50 GB, 403 million line log opens immediately, and a 50 million row CSV opens as a sortable grid, well past Excel's row limit. The full methodology is at caxton.app/docs/benchmarks.
Features include find and replace with exact counts, Find in Files, a log mode with Go to Time and severity filters, file compare, 18 encodings, column transforms with a preview, validation with repairs, column profiles, removing duplicates, and Paste Special.
Caxton Free opens, searches and filters any file at no cost. Caxton Pro adds editing and saving, monthly, yearly, or as a lifetime license. 7-day trial of everything, no card.
