Bug: org-table-import fails to import xlxs files

Bug: org-table-import fails to import xlxs files

[swedebugia]

Hi

Thanks for a making this fantastic program!

I think I found a bug.

When trying to import a xslx table into org-mode I get a lot of binary
data instead of a table back.

I would rather either get an error saying it is not supported yet or an
org-table.

Recoll supports xlsx files it seems, so it should be possible
with python 3 at least to make this work also in org-mode. See
https://www.lesbonscomptes.com/recoll/pages/features.html

I found this in Arch:
$ pacman -Ss xlsx
community/python-openpyxl 3.0.5-1
    A Python library to read/write Excel 2007 xlsx/xlsm files

Other ones written in python:
https://github.com/dilshod/xlsx2csv (not that active)
https://github.com/wireservice/csvkit (active)

Also gnumeric can convert it:
The Gnumeric spreadsheet application comes with a command line utility
called ssconvert that can convert between a variety of spreadsheet
formats:

$ ssconvert Book1.xlsx newfile.csv
Unfortunately it is only available with the gnumeric GUI currently
which is ~14MB bloat.

I also found this nice and small rust program that works well:
https://github.com/zitsen/xlsx2csv.rs
It is surprisingly large though:
8.7M Sep 12 16:53 .cargo/bin/xlsx2csv
Which is way more than ssconvert, but on the other hand it does not
require any gnome dependencies or GUI stuff:
38K Sep  5 16:21 /usr/bin/ssconvert

cheers

Just for fun I compared the speed, and the found that ssconvert is
slower by a factor of 10 on a ~4500 line spreadsheet.

$ time xlsx2csv test.xlsx 
* Preparing write to ./Tabelle1.csv
** sheet range size is (4770, 11)
** Starting writing
** Done with sheet
`Tabelle1` real	0m0.565s
user	0m0.537s
sys	0m0.021s

$ time ssconvert
test.xlsx test.csv

real	0m4.249s
user	0m4.186s
sys	0m0.061s

Indeed!  Let's have Org throw an error in such cases, I made this
change in master as 9c31cba00.

Thank you!

Do you have any idea how I can setup org-mode to use a convert
tool before trying to import?

cheers
