ASS 转 JSON

格式转换Advanced SubStation Alpha（ASS）

或者粘贴字幕文本

这次转换会改变什么

有 1 项会被丢弃或需要你决定

格式专有内容
源格式保留在字幕条之外的内容（非字幕块、文件头文字、单条字幕的设置、被注释掉的事件）——目标格式没有地方存放它们

这份清单来自这两种格式的能力矩阵，而不是你加载的这份具体文件。如果具体文件用到了格式允许、但矩阵没有建模的特性，可能会丢得更多。

这一页把 ASS 脚本转成 JSON。适合交给脚本处理、做两份文件的字段比对，或者放进版本库看每次改动——ASS 的纯文本脚本在这些场景里并不好用。

产物里每条字幕是一个对象：id、start、end 与 lines 数组，时间是整数毫秒，ASS 的 0:00:04.13 写成 4126。脚本的标题和整张样式表都会保留：样式表的每一列都在，包括本站没有专门建模的列，另外还给出解析后的字体、字号、颜色与粗斜体标记。

JSON 装不下的是 ASS 的私有构造：[Script Info] 里除标题外的全局键（PlayResX、WrapStyle、Collisions 等）、非 Dialogue 的事件行（Comment:、Picture:、Sound:），以及 [Fonts] 与 [Graphics] 里内嵌的字体和图形。它们不是字幕，会按有损说明逐项列出。

输出统一为 UTF-8、Unix 换行、无 BOM。一次可以拖入多个文件，串行处理、可以取消，最后打包成 ZIP；整个转换在浏览器里跑，文件不上传。

常见问题

ASS 转 JSON 时，样式表的列会全部保留吗？

会，整张表按列搬进 styles，连本站没有专门建模的列也在；另外还给出解析后的字体、字号、颜色与粗斜体标记。

ASS 转 JSON 后 0:00:04.13 变成什么？

4126，整数毫秒。不四舍五入，也不改写成时间码字符串。

ASS 转 JSON 会保留 Comment: 和 Picture: 事件吗？

不会。只有 Dialogue 行成为 cue；Comment:、Picture:、Sound: 这些非字幕事件没有对应结构，会被丢弃。

ASS 转 JSON 时 [Script Info] 里的 PlayResX 去哪了？

丢弃。JSON 只保留标题，WrapStyle、Collisions 等其余全局键也没有落点；这是这个方向唯一的有损项。

ASS 转 JSON 后一条两行字幕怎么存？

存在同一条 cue 的 lines 数组里，两个元素仍属于同一条字幕，播放器会一起显示。

ASS 转 JSON 的内嵌字体会跟着走吗？

不会。[Fonts] 与 [Graphics] 是给渲染器的附件，不是字幕，JSON 结构里没有它们的位置。

JSON 转回 ASS 会损失什么？

精度：JSON 的毫秒写进 ASS 只能保留到百分秒，最多相差 5 毫秒。
