Content-Transfer-Encoding: binary
Content-ID: <jsonInfos>

{"messages":[{"id":"0","type":"INFOS","messageContent":"La requête a été traitée avec succès","replacementValues":[]}]}

I tried in python:

with open('tmp.txt', 'r') as tmp:
     with open('sample.pdf', 'wb') as sample:
          sample.write(tmp.read().encode('utf-8'))

You cannot get back your original pdf files from plain text files only. Because while exporting to txt, the converter chops of a lot of information like color encoding, structure, font data etc. However, if you just want to create pdf from txt, you can use wkhtmltopdf and pdfkit to achieve that.

  • Install wkhtmltopdf via apt-get install wkhtmltopdf

  • Install pdfkit via pip install pdfkit.

Now you can just do this:

import pdfkit

pdfkit.from_file("tmp.txt", "sample.pdf")

This will return:

libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
Loading page (1/2)
Printing pages (2/2)                                               
Done                                                           
True

The pdf file should look like this:

You can consider using FPDF to generate PDF file. PFB the sample code.

from fpdf import FPDF

with open('tmp.txt', 'r') as tmp:
    wpdf = FPDF()
    wpdf.set_font('arial', '', 12)
    wpdf.add_page()
    wpdf.set_xy(10, 5)
    for line in tmp:
        wpdf.cell(50, 5, txt=line, ln=1, align="L")
    wpdf.output('sample.pdf', 'F')`enter code here`

Please refer below link for more information. https://pyfpdf.readthedocs.io/en/latest/Tutorial/index.html

You cannot write to pdf files like you write to normal text files. There are libraries in python to write pdf files. you can try pdfrw.

the data you are going to write to pds can have attributes(other than the text you save in text files) follow the samples to do what you actually need:

from pdfrw import PdfWriter
y = PdfWriter()
y.addpage(data)
y.write('result.pdf')
