42 Editor is a code and text editor for iPhone and iPad. It opens the files you already have, in the Files app, iCloud Drive, Working Copy, Dropbox or any other file provider, and saves your changes back to the same file. There is nothing to sign in to and nothing is uploaded.
Sometimes the file that needs fixing is a config file, a script or a spreadsheet export, and the only device to hand is a phone. 42 Editor is made for those moments.
EDIT IN PLACE
• Open a file or a whole folder from any provider in the Files app. Your changes go back to the original.
• Opened folders are remembered: create, rename, duplicate and delete files and folders inside them.
• Recent files reopen with one tap.
• Open in 42 Editor from the Files app and the share sheet.
SYNTAX HIGHLIGHTING FOR 29 LANGUAGES
Python, Swift, JavaScript, TypeScript, C, C++, Objective-C, C#, Java, Kotlin, Go, Rust, PHP, Ruby, Dart, Lua, R, JSON, YAML, TOML, INI, XML, HTML, CSS, Markdown, Shell, SQL, Makefile and Dockerfile, in light and dark. Line numbers with the current line marked, and long lines that wrap or scroll sideways.
A KEYBOARD ROW FOR CODE
Tab and outdent, a comment toggle, cursor keys, undo and redo, and the brackets and symbols the iOS keyboard hides. Auto-indent, optional closing of brackets and quotes, and tabs or spaces at 2, 4 or 8 wide.
FIND, REPLACE AND FORMAT
• Find and Replace, Go to Line, toggle comment, and indent or outdent a selection.
• Format or minify JSON, keeping the order of the keys.
• Markdown and HTML preview, a tap away.
CSV AND TSV AS A TABLE
A grid with a pinned header row. Edit cell by cell; add, duplicate or delete rows and columns; sort, filter and undo. The raw text is one tap away.
CAREFUL SAVING
42 Editor keeps each file's text encoding (UTF-8, UTF-16 or Windows-1252), its line endings and its final newline. It autosaves two seconds after you stop typing, and if another app changed the file in the meantime it stops and asks which version to keep.
iPHONE AND iPAD
System, light or dark appearance, font size from 9 to 32 pt, and ⌘S to save on a hardware keyboard.
PRIVATE
No account, no ads and no analytics. Your files stay on your device and in the providers you choose.
42 Editor is an editor, not a place to run code: it doesn't compile or run anything.
