Lotus-1-2-3 (wk1) file parsing guidelines

Question

I'm trying to make a little converter from wk1 (lotus-1-2-3) files to excel for a friend. The files have only simple data, no functions or anything really complicated.

I couldn't find anything related to guidelines to parse or documentation of wk1 file structure. I already tried going through libreoffice code but my C++ is very rusty (academic level, 6 years ago).

I usually code in PHP and JavaScript, and I didn't find anything related to this for these languages.

I believe I read somewhere that Lotus-1-2-3 is abandonware now, so I don't think is "illegal" or anything.

Is there any information available about this? What would be the best approach to "decoding" the data (other than that just give up)?

Thanks

对我来说没有理由重新发明轮子......

有一个可以转换这些文件的免费软件 它甚至可以作为便携式应用程序使用，它有一个命令行参数来转换格式：
soffice --headless --convert-to <TargetFileExtension>:<NameOfFilter> file_to_convert.xxx

所以，如果你真的需要一个“自己的”程序：用libreoffice的可移植版本打包它，并创建一个很好的界面来选择源文件和目标文件并运行命令行......
