JSON Formatter for Mac
Stop pasting private JSON into web formatters. TextStow lets you format, beautify, and compress JSON copied from APIs, logs, and config files — all processed locally on your Mac.
API Debugging Creates Messy JSON
Developers and QA engineers copy JSON from browser dev tools, API responses, log files, and terminal output daily. Minified responses are nearly impossible to read, and pasting them into web formatters exposes private API keys, customer data, and internal endpoints to third-party servers.
Format JSON Locally Without Opening a Browser
Copy any JSON payload from your clipboard and format it with TextStow built-in JSON tool directly from the menu bar. Get readable, indented output with proper syntax highlighting — without sending data to a remote website or breaking your development flow.
Compress JSON for Sharing and Documentation
Need to share a compact JSON payload in Slack, Jira, or API documentation? TextStow can minify formatted JSON back to a single line. Perfect for embedding in code comments, config files, or chat messages where whitespace matters.
Keep Sensitive Data Off Online Tools
API responses often contain authentication tokens, user emails, internal IDs, and business logic. Online JSON formatters require you to paste this data into their servers. TextStow processes everything locally — your JSON never leaves your Mac.
History Makes Responses Recoverable
Because TextStow is also a clipboard manager, the original minified JSON and your formatted output both remain in your searchable history. Find any API response you copied earlier this week, even after closing your browser or terminal.
Offline JSON Formatter for Mac Menu Bar
When your internet is unstable or you are working on air-gapped systems, web formatters are useless. TextStow JSON formatter runs entirely offline, available from your menu bar with zero network requests. Format JSON anywhere, anytime.
