有没有办法使用 python 将.pdf 转换为.csv？

Question

I'm currently experimenting with tabula-py, but all documentation samples I tried when extracting pdf data resulted in the following error: returned non-zero exit status 1.

So I'm just curious if there is other ways to convert data in tables on a pdf to a csv file using python.

Answer 1

The answer for tabula-py is already available on StackOverflow & other resources.. to try using Camelot:

pip install camelot-py[cv]


import camelot
tables = camelot.read_pdf('X.pdf')
tables.export('X.csv', f='csv', compress=True) # you can also save it different file formats

Answer 2

If you are looking to export tables from PDF to CSV files using Python the best way it to use libraries like Taluba and Camelot.

First we'll need to extract tables from individual pages and then libraries like pandas to export them into CSVs or other required formats.

However, if the documents are non-electronic, we'll have to use OCR or ML techniques to extract tables.

Here's a blog post which has a few examples: https://nanonets.com/blog/pdf-table-to-csv/#pdf-table-extraction-to-csv-with-python
