Open and edit plain text files from Files with SimpleTextEditor. Work with TXT, Markdown and JSON, with JSON formatting when you need it.

Edit the file where you keep it

SimpleTextEditor works with plain text files from the Files app, including iCloud, On My iPhone and supported file providers. It is useful when someone sends a TXT file or you need to change a Markdown or JSON file on your phone.

Make one clear change

Open the actual file, find the part you want to edit and change the text. Save it back, then reopen it to confirm the result. For JSON, the published app provides a formatting action that makes the structure easier to read. Formatting is useful for inspection; it does not establish that a configuration will work in another app.

Choose plain text deliberately

Markdown remains text with formatting markers. JSON remains structured text. Use this app when you want the file itself, rather than a rich-text document. If the file belongs to a service or another project, keep a copy before making a consequential edit.

Get started with SimpleTextEditor
