Before you paste that HAR file into ChatGPT: three leaks, and the local tool I built instead

Description and use

<p>Every developer has done this: an API call fails, you copy the request from DevTools, decode the token somewhere, convert a timestamp somewhere else, and finally paste the whole thing — headers, cookies, token and all — into ChatGPT, a GitHub issue or a support ticket.</p> <p>That last step is where things can go wrong.</p> <h2> Three public reminders </h2> <p><strong>1. Code formatters that saved everything.</strong></p> <p>In November 2025, watchTowr Labs reported that the “save/share” features of JSONFormatter and CodeBeautify had exposed 80,000+ saved snippets, including Active Director
