如何使用Python和openpyxl复制Excel行并过滤值？

Question

I have a gigantic excel workbook with a lot of personal data. Each person has a unique numeric identifier, but has multiple rows of information.

I want to filter all the content through that identifier, and then copy the resulting rows to a template excel workbook and save the results. I'm trying to do this with Python and openpyxl.

I thought that applying an AutoFilter and then copying the results would solve the problem. But it seems that openpyxl can only apply the AutoFilter and not do the actual filtering?

I tried to follow the answer to this question , but it won't do anything. I want to filter the number in column D (4).

import openpyxl, os
from openpyxl.utils import range_boundaries

#Intitializes workbooks
print('Opening data file...')
min_col, min_row, max_col, max_row = range_boundaries("A:AG")
wb = openpyxl.load_workbook('Data.xlsx')
ws = wb.active
template = openpyxl.load_workbook('Template.xlsx')
templatews = template.active

#Asks for numeric identifier
print('Done! Now introduce identifier:')
filterNumber = input()

#Does the actual thing
for row in ws.iter_rows():
    if row[3].value == str(filterNumber):
        templatews.append((cell.value for cell in row[min_col-1:max_col]))

#Saves the results
template.save('templatesave.xlsx')
print('All done! Have fun!')

Any insight on this will be appreciated. Thanks!

EDIT: corrected column number according to @alexis suggestion, although it has not solved the issue.

SOLVED: it turns out that the IF statement asks for an integer, not a string. Using int() solved the problem.

for row in ws.iter_rows():
    if row[3].value == int(filterNumber):
        templatews.append((cell.value for cell in row[min_col-1:max_col]))

Answer 1

The iter_rows() method returns a sequence of tuples, so they're indexed from zero: column D is at index 3. In other words, try it this way:

for row in ws.iter_rows():
    if row[3].value == str(filterNumber):
        ...

If it doesn't work, have your script print some of the column's values and take it from there. Maybe this cell's format is not what you expect, etc.

Answer 2

I finally solved it! It turns out, that

for row in ws.iter_rows():
    if row[1].value == int(filterNumber):
        templatews.append(cell.value for cell in row[min_col-1:max_col])

Asks for an integer and not a string in the IF statement. Using the int() method solved the problem.
