LightBlack工具，由论坛大佬原创制作的一个Excel工具箱软件，能实现Excel搜索查询，PDF转Word等功能，优点是单文件程序，操作方面，无需多个软件来回切换，全部功能免费使用，方便经常需要转换的朋友们操作体验。本次带来LightBlack1.00首发版下载，有相关PDF工作转换需求的朋友们可以下载使用。
LightBlack使用说明
新的软件操作简单，先导入文件然后单击按钮就可以了（其实刚设定的时候连按钮都没，直接导入就自动转换了，后面想想，可能有些人不喜欢这种模式，所以改回了传统鼠标单击按钮），现在是可拖放也可导入，随便了，其他我做了限制，不是规定文件不能转换，比如Word转PDF，你导入PDF然后点击Word转PDF就不行，没办法不设置，到时候又软件有bug，转换完，会在左下角提示转换成功和文件路径的
