Hello!
My name is Eric and I have a problem.
I committed the mistake of not saving a project I worked on during hours.
However I did export it to PDF and HTML.
My question is, Is it possible to gather the data from HTML and import it back to GanttProject?
Thank you for your help!
The best way in such cases is using Help > Recover. It scans through auto-saved files and suggests restoring project from them.
With respect to PDF and HTML, it is surely possible to gather data from them, the matter is how much time and efforts does it cost. There is no built-in import from PDF/HTML in GanttProject, sorry.
