My wife ask me to convert few of PDF files to Excell spreadsheet. I did same thing last year by creating some small scripting program in python to do the conversion, but I don’t know where I put my code right now. Maybe lost during formating my laptop last year..haha :stuck_out_tongue_winking_eye:

I am 懒 right now (guess what I wrote in hànzì) and I don’t remember how I did last time. Hahaha.. With my Google-fu skill, I found out DfTables offer free API for converting document to another format. Nice! :grimacing:

Fedora 30 comes with python 3.7 installed. Sadly, dftables.com API doesn’t currently work on 3.7 :astonished: but no worries since we can create virtualenv to load Python 3.6

Now let install the virtualenv into our workstation, take note I don’t use sudo since my account have administration access, so load with --user args should be enough. I don’t like run something and everthing with sudo.

$ pip3 install --user virtualenv

Download python 3.6 with DNF

$ sudo dnf install python36

Create some directory and cd to that directory. For example I am using ~/workstation/PDF-to-Excell. We will use python 3.6 to install the new python environment:

$ cd ~/workstation/PDF-to-Excell
$ virtualenv --python=/usr/bin/python3.6 python36

now step into the environment using

$ source python36/bin/activate

you should get something like this:

(python36) [rnm@robbinespu PDF-to-Excell] $ python --version
Python 3.6.9

Now let try install DfTables pips

(python36) [rnm@robbinespu PDF-to-Excell] $ pip install git+https://github.com/pdftables/python-pdftables-api.git

It working, nice! Currently, We have isolated python 3.6 virtual enviroment and successfully installing required pips for Pdftables dependencies and now, let have some fun 🥰
