面向生产环境的实用工具与排错知识库

少一点猜测,更快恢复服务。

Ovalk 将高频小工具和结构化排错流程放在同一个地方。先定位,再验证,最后留下可复用的预防动作。

先完成手上的动作

计算和格式化在浏览器中完成,不会保存或上传输入。工具控件采用英文技术术语,计算结果与标准格式不受语言影响。

JSON: what formatting changes

Format adds two-space indentation; Minify removes unnecessary whitespace. Invalid JSON is left unchanged. Keys must be double-quoted; comments and trailing commas are not valid JSON. For example, {"ok":true} is valid; {ok:true,} is not.

This uses JavaScript’s JSON parser, not a lossless editor: large integers can lose precision, duplicate keys keep the final value, and formatting can change key order or number notation. Keep identifiers larger than 9,007,199,254,740,991 as strings. Preserve the original when exact representation matters. Processing is limited to 5 million characters.
