concat pdf tables into one excel table using python
I'm using tabula in order to concat all tables in the following pdf file
To be a one table within excel format.
Here's my code:
from tabula import read_pdf
import pandas as pd
allin = []
for page in range(1, 115):
table = read_pdf("goal.pdf", pages=page,
pandas_options={'header': None})[0]
allin.append(table)
new = pd.concat(allin)
new.to_excel("out.xlsx", index=False)
Also i tried the following as well:
from tabula import read_pdf
import pandas as pd
table = read_pdf("goal.pdf", pages='all', pandas_options={'header': None})
new = pd.concat(table, ignore_index=True)
new.to_excel("out.xlsx", index=False)
Current output: check
But the issue which am facing that from page# 91 i start to see the data not formatted correctly within the excel file.
I've debug the page individually and i couldn't figure out why it's formatted wrongly especially it's within same format.
from tabula import read_pdf
import pandas as pd
table = read_pdf("goal.pdf", pages='91', pandas_options={'header': None})[0]
print(table)
Example:
from tabula import read_pdf
import pandas as pd
table = read_pdf("goal.pdf", pages='90-91', pandas_options={'header': None})
new = pd.concat(table, ignore_index=True)
new.to_excel("out.xlsx", index=False)
Here I've ran the code for two pages 90 and 91.
starting from row# 48 you will see the difference here
Where you will notice the issue that name and address placed into one cell. And city and state placed into one call as well
I digged in source code and it has option columns and you can manually define column boundaries. When you set columns then you have to use guess=False.
tabula-py uses program tabula-java and in its documentation I found that it needs values in percents or points (not pixels). So I used program inkscape to measure boundaries in points.
from tabula import read_pdf
import pandas as pd
# display all columns in dataframe
pd.set_option('display.width', None)
columns = [210, 350, 420, 450] # boundaries in points
#columns = ['210,350,420,450'] # boundaries in points
pages = '90-92'
#pages = [90,91,92]
#pages = list(range(90,93))
#pages = 'all' # read all pages
tables = read_pdf("goal.pdf",
pages=pages,
pandas_options={'header': None},
columns=columns,
guess=False)
df = pd.concat(tables).reset_index(drop=True)
#df.rename(columns=df.iloc[0], inplace=True) # convert first row to headers
#df.drop(df.index[0], inplace=True) # remove first row with headers
# display
#for x in range(0, len(df), 20):
# print(df.iloc[x:x+20])
# print('----------')
print(df.iloc[45:50])
#df.to_csv('output-pdf.csv')
#print(df[ df['State'].str.contains(' ') ])
#print(df[ df.iloc[:,3].str.contains(' ') ])
Result:
0 1 2 3 4
45 JARRARD, GARY 930 FORT WORTH DRIVE DENTON TX (940) 565-6548
46 JARRARD, GARY 2219 COLORADO BLVD DENTON TX (940) 380-1661

EDIT:
It may need also option area (also in points) to skip headers. Or you will have to remove first row on first page.
I didn't check all rows but it may need some changes in column boundaries.
EDIT:
Few rows make problem - probably because text in City is too long.
col3 = df.iloc[:,3]
print(df[ col3.str.contains(' ') ])
