The Problem with Most Online Formatters
You know the drill. You paste some JSON into a random online formatter, or convert a CSV to Markdown, or format a WeChat article. The tool works fine, but have you ever stopped to think about what happens to your data?
Most "free" online tools send your content to their servers. Some store it. Some log it. Some sell aggregated data. You have no idea where your sensitive JSON payload, proprietary CSV data, or internal documentation ends up.
The Client-Side Alternative
I built tools.pixiaoli.cn — a collection of 33+ developer utilities that run entirely in your browser. No server uploads. No data collection. Your content never leaves your machine.
