Python Pandas dataframe reading exact specified range in an excel sheet

Question

I have a lot of different table (and other unstructured data in an excel sheet) .. I need to create a dataframe out of range \'A3:D20\' from \'Sheet2\' of Excel sheet \'data

Answer 1

One way to do this is to use the openpyxl module.

Here's an example:

from openpyxl import load_workbook

wb = load_workbook(filename='data.xlsx', 
                   read_only=True)

ws = wb['Sheet2']

# Read the cell values into a list of lists
data_rows = []
for row in ws['A3':'D20']:
    data_cols = []
    for cell in row:
        data_cols.append(cell.value)
    data_rows.append(data_cols)

# Transform into dataframe
import pandas as pd
df = pd.DataFrame(data_rows)
