Reading Excel file without hidden columns in Python using Pandas or other modules

Question

Can anyone tell me how to read the Excel file without hidden columns in Python with Pandas or any other modules?

When I try to read excel file using Pandas, for exam

Answer 1

I don't think pandas does it out of the box.

Input

You will have to unfortunately do some redundant reading (twice). openpyxl does what you want -

import openpyxl
import pandas as pd

loc = 'sample.xlsx'
wb = openpyxl.load_workbook(loc)
ws = wb.get_sheet_by_name('Sheet1')

hidden_cols = []
for colLetter,colDimension in ws.column_dimensions.items():
    if colDimension.hidden == True:
        hidden_cols.append(colLetter)

df = pd.read_excel(loc)
unhidden = list( set(df.columns) - set(hidden_cols) )
df = df[unhidden]
print(df)

Output

    C   A
0   1   7
1   9   7
2   5  10
3   7   7
4   4   8
5   4   6
6   9   9
7  10   3
8   1   2

Explanation

Reading the file first using openpyxl -

loc = 'C:/Users/FGB3140/Desktop/sample.xlsx'
wb = openpyxl.load_workbook(loc)
ws = wb.get_sheet_by_name('Sheet1')

Searching for hidden property in cells (this is where the hidden columns are captured)

hidden_cols = []
for colLetter,colDimension in ws.column_dimensions.items():
    if colDimension.hidden == True:
        hidden_cols.append(colLetter)

Read the same file using pandas - df = pd.read_excel(loc)

Find the unhidden columns by subtracting the hidden ones from the rest -

unhidden = list( set(df.columns) - set(hidden_cols) )

Finally, filter out the unhidden columns -

df = df[unhidden]

P.S

I know I could have done colDimension.hidden == False or simple if not colDimension.hidden - The goal here is to capture the hidden columns and then do the filtering accordingly. Hope this helps!
