JSON Formatter for Mac
Copy JSON from an API response, log, or config file, then format or minify it from the TextStow Mac app. This is a clipboard workflow inside TextStow, not an online formatter embedded in this web page.
Usage Examples
Format API responses
Copy a minified JSON response from browser dev tools or Postman, format it locally, and paste the readable version into your code review.
Compress for sharing
Minify a formatted JSON config file to a single line for embedding in a Slack message or Jira ticket.
Debug log payloads
Copy a one-line JSON log entry, format it to identify the key causing the error, then bookmark it for reference.
Behavior and Limitations
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 Tool
Copy a valid JSON payload, open the TextStow text tools from the Mac menu bar, choose the JSON formatting action, and copy the indented result. The action converts structural whitespace for readability; it does not infer missing commas, quotes, or braces in malformed JSON.
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 the Transformation in the Mac Workflow
API responses can contain authentication tokens, user emails, internal IDs, and business logic. A local formatting action reduces the need to paste that payload into an unrelated website. You should still remove secrets before sharing the formatted result in chat, tickets, documentation, or code review.
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.
Know What This Page Offers Before You Download
This page explains the JSON workflow available in the TextStow Mac app; it does not contain an interactive web formatter. If you need a browser-based tool with no installation, this page is not the result you want. If JSON frequently enters your clipboard and you want formatting beside history and bookmarks, download TextStow and use the app action.

Does this web page format JSON?▾
No. The formatting action is part of the TextStow Mac app. This page documents the workflow and its limits.
Should I remove secrets from API responses?▾
Yes. Local formatting reduces unnecessary data transfer, but tokens and personal data should still be removed before the result is shared.
Can I compress JSON back to a single line?▾
Yes. TextStow can minify formatted JSON back to a compact single-line payload for sharing or embedding.
Does the JSON formatter work offline?▾
Yes. The JSON formatter runs entirely offline on your Mac with no internet connection required.
Can I find formatted JSON later in my clipboard history?▾
Yes. Both the original JSON and formatted output are saved in your searchable clipboard history.
What JSON size can TextStow handle?▾
TextStow is intended for clipboard-sized API responses, log payloads, and configuration snippets. Use a code editor or command-line tool for very large files.
