Convert PDF file to CSV in Ubuntu 18.04

Hi to all. Currently, i need to convert a pdf file into a csv file. The original PDF comes from our payroll software, and i need to convert it into a csv to generate some reports for our company's board.
So far, i have used pdftotext to create the txt file:

pdftotext -nopgbrk -layout ACUM\ EMPLEADOS\ DIC\ 2019-2.pdf try1.txt

Then used sed to create the csv file:

sed 's/ \+/,/g' try1.txt > try1.csv

This is the output i get:

,COMPANYNAME

So far, it seems right, however, i need the CSV file to have the following format so it can be read from an external API to process the data:

My idea is to create a simple shellscript that can do this. Any suggestions to accomplish this?, thanks in advance.
