Extracting Data into Columns using pdfplumber - arvin - Dec-13-2022

I have a pdf which has data in tabular format and has 6 columns but the columns are not separated by boundaries so when I extract the data using pdfplumber, all the data comes in one cell only and I want in separate cells.

How could I do that?

Thanks in advance

Looks like each line of your data is separated by a space.

If that is so, just use .split() on each line to get a list of each item of data in the line.

The list can then be written to Excel or, I remember Menator mentioned a module called tabulate which formats text data nicely!

I thought of the same thing, but some lines contain more data and some lines contain less.

Which method do you use to extract the data from a page?

Quote:table = pdf.pages[0].extract_table()
df = pd.DataFrame(table[1:])

What exactly is table? Actual text? Bytes? Or some kind of pdfplumber object?

Are column headers included in table?

I'm starting to understand your problem!

Using reportlab I made a very simple pdf with 1 table of 4 rows and 5 columns. The table had borders.

The data for the table looks like this:

Quote:data= [['00', '', '02', '', '04'],
['10', '', '12', '', '14'],
['20', '', '22', '', '24'],
['30', '', '32', '', '34']]

As you can see, the columns 2 and 4 contain no data, just ''

Using this, I got the data from the table:

import pdfplumber
# Parse pdf
with pdfplumber.open(path2pdf + savename2) as pdf:
         # Get the first page of the object
    page = pdf.pages[0]
         # Get the text data of the page
    text = page.extract_text()
         # Get all the tabular data of this page
    tables = page.extract_tables()
         # Traversing table
    for t_index in range(len(tables)):
        table = tables[t_index]
                 # Traversing each row of data
        for data in table:
            print(data)
Which gives this as output, you can see the empty values, so they should be in your pandas df as NaN, I suppose.

Output:
['00', '', '02', '', '04']
['10', '', '12', '', '14']
['20', '', '22', '', '24']
['30', '', '32', '', '34']
But when I make a table with no borders, there is no table, just text:

Quote:>>> tables
[]
>>> text
'00 02 04\n11 13\n20 22 23 24\n30 31 32 34'
>>>

Now how to know which columns in which rows have nothing in them??

Think think!

I also tried Tabula, but I had no luck.

RE: Extracting Data into Columns using pdfplumber - Pedroski55 - Dec-15-2022

Try this then look at table!

import pdfplumber
import re

path2pdf = '/home/pedro/myPython/reportlab_python/my_pdfs/'
savename1 = "simple_table1.pdf" # no borders

pdf = pdfplumber.open(path2pdf + savename1)
 
for page in pdf.pages:
    print(page.extract_text())
    for pdf_table in page.extract_tables():
        table = []
        cells = []
        for row in pdf_table:
            if not any(row):
                # If a line is all empty, it is considered to be the end of a record
                if any(cells):
                    table.append(cells)
                    cells = []
            elif all(row):
                # If the line is not empty, then this line is a new line, the last one ends
                if any(cells):
                    table.append(cells)
                    cells = []
                table.append(row)
            else:
                if len(cells) == 0:
                    cells = row
                else:
                    for i in range(len(row)):
                        if row[i] is not None:
                            cells[i] = row[i] if cells[i] is None else cells[i] + row[i]
        for row in table:
            print([re.sub(' +', ' ', cell) if cell is not None else None for cell in row])
            #print([re.sub(' +', ' ', cell) if cell is not None else ' ' for cell in row])
        print('---------- Dividing line ----------')
 
pdf.close()
Output:
>>> table
[['00', '', '02', '', '04'], ['10', '', '12', '', '14'], ['20', '', '22', '', '24'], ['30', '', '32', '', '34']]
>>>
Then you can put table in pandas, I hope!
