Corporate IT policies routinely block users from installing software on their work machines. The lockdown is well-intentioned: every install is a potential supply-chain risk, a license-tracking obligation, and an attack-surface expansion. But the policy creates a real cost when an analyst or engineer needs a one-off tool for a one-off task. The alternative paths are an IT ticket (slow), shadow IT on a personal machine (compliance risk), or a SaaS tool with vendor evaluation (slow plus compliance). A pure browser-based tool sidesteps all three paths because there is no software being introduced into the environment.
FixTools runs as static HTML, CSS, and JavaScript served over HTTPS. Nothing is downloaded to the user's machine beyond standard browser cache, nothing is installed, and nothing requires elevated permissions. The conversion itself happens in JavaScript inside the browser sandbox, which is the same execution environment that runs every web page the user visits. From an IT-policy perspective, using FixTools is no different from reading a blog or filling in a web form.
Operating-system independence is a side benefit. The tool works identically on Windows, macOS, Linux, ChromeOS, iPadOS, and Android. There is no Windows-only version, no Mac-only installer, no Linux package missing for your distribution. Whatever device you happen to be on, the conversion experience is the same. This is particularly useful for consultants moving between client environments, where the device of the day varies but the workflow requirements do not.
The trade-off versus installed tools is performance and offline-first behaviour. A native Python script with pandas can stream-parse very large JSON files using ijson and write CSV without holding the whole dataset in memory, which is hard to replicate in a browser. For the file-size ranges that matter to most users (under 200MB), the browser keeps up fine. For larger files, an installed tool is the right answer. For everything else, no-install is the better trade.
