Neat Nest: JSON & Text Editor

Neat Nest is a text editor that turns into a JSON viewer, formatter and compare tool. Open any text file. When it is JSON, switch between Text, Tree and Table views of the same document, filter it with JSONPath, and compare two files side by side.

One editor for text and JSON
• Opens JSON, plain text, logs, CSV, Markdown, YAML, XML and config files
• Line numbers, find and replace, undo and redo, word wrap or sideways scrolling
• A key row over the keyboard with braces, brackets, colon, comma, quote and Tab
• Invalid JSON still opens as text. The status bar shows the exact line and column of the first error, and one tap takes you there
• The path of the value under the cursor, ready to copy

Tree and Table views
• Tree: open and close objects and arrays, edit any value, delete, copy a value or its path
• Table: arrays of objects as rows and columns, nested keys as dotted columns, sort by any column
• Format, Compact and Sort keys in one tap, with 2 or 4 spaces

Compare two JSON files
• Key order and formatting do not count as a change
• Array items are lined up by value, so an inserted item does not mark the rest as changed
• Counts of added, removed and changed values, with Previous and Next to step through each difference
• Side by side on a tablet or in landscape, one aligned list on a phone. Every change is marked with a sign as well as a colour

JSONPath filter
Filter the Tree or Table with queries like $..id or items[?(@.price > 10)], with slices, wildcards, deep search and regular expressions.

Your file, exactly
• Saves back to the file you opened, or Save as a copy
• Keeps numbers exactly as written, even very large ones, through format, sort and tree edits
• Warns about duplicate keys and numbers that other apps may round
• Never adds a byte order mark, keeps your line endings, and does not escape letters or emoji
• Your open documents are kept on the phone as you type, so switching apps never loses an edit

Opens from other apps
Pick Neat Nest when you open a text or JSON file from your file manager, email or cloud storage app, share text or a file to it, or select JSON in any app and choose Open in Neat Nest. Two home screen widgets give quick actions and your recent files, and the app icon has shortcuts.

Big files
Files up to 20 MB open. Up to about 800 KB the Text view edits everything; larger files scroll in a read only Text view, and you edit their values in the Tree view.

Private and simple
• One purchase, every feature, no subscription
• No ads, no account, no tracking
• Works fully offline. The app asks for no permissions at all, not even internet access
• Light, dark and black themes, large touch targets, TalkBack labels and text up to 200 percent
