Peter,
I consider this important, and have struggled with this in the past.
There are a number of means to back convert from pdf. Most will preserve
the text, but many will not preserve the layout and formatting data. A
number of on line services will allow you to upload and convert to MSWord
(.docx) and Libreoffice will read the .docx. There are a few that work
well, but we, as a rule do not use these services because of the widespread
and rampant data harvesting from internet companies. We believe there is
substantial risk to sensitive personal and company information, so that
leaves well vetted programs.
I've had reasonable success at high res, ocr scanning but color rendition
is lost or distorted. Sourceforge and GIT offer a number of open source
programs.
There is an older thread
https://ask.libreoffice.org/t/how-to-convert-pdf-to-odt/12268/8 that has
some helpful suggestions, but many are upload to internet and translate
downloads.
I've used okular (KDE) on FreeBSD but formating loss is evident.
This is something I think everyone would like, but I don't know enough
about the .pdf internal formats to know if the {odt, docx, ...} is a loss
free translation or if .pdf writers lose formating information in the .pdf
generated file. If anyone knows where the .pdf spec is found I can take a
look at it and see how hard it would be. I suspect, though that since it
isn't done well in many cases, it is not an easy back conversion to do.

Hello All,
I recently created a file consisting of 1 page, containing a 4 column
table and exported it to PDF, foolishly failing to save the original in
ODT. Does anyone know of a means of reversing the export to reproduce
the original, editable ODT file?
I know that this is not very important, but it would be nice if the
possibility existed, thus avoiding the tedium of re-typing the document.
Regards.
Peter HB
