How do i get value present in a merged cell

问题

I want to get value of a merged cell that has range from D3 to H3 using openpyxl library. As per my understanding most libraries read data from 1st cell itself. Thus the merged content is present in it but I get a none value when I read it.

Following is my code:

wb = load_workbook(work_directory_path+'/outputs/report_vap.xlsx')
ws = wb.get_sheet_by_name("Summary")
suite_path = ws.cell('D3').value
if not isinstance(suite_path, unicode):
    value=unicode(suite_path)
value=value.encode('utf8')
print "Suite Location is "+value;

The output is : Suite Location is None

The value in cell for D3 to H3 is : c:\users\xyz\desktop\abc\c++\events\comevents

I even tried printing all the values in the sheet but except for integer values all values returned None.

Following is the changed code:

wb = load_workbook(work_directory_path+'/outputs/report_vap.xlsx')
ws = wb.get_sheet_by_name("Summary")
for row_index in range (ws.get_highest_row()):
    for col_index in range (ws.get_highest_column()):
        print ws.cell(row=row_index, column=col_index).value
suite_path = ws.cell('A11').value
print suite_path
if not isinstance(suite_path, unicode):
   value=unicode(suite_path)
value=value.encode('utf8')
print "Suite Location is "+value;

The output is:

None

None None None None None None None None None None None None None None

None

None None None None None None None None None None None None None None None None None

None None None None None None None None None None None None None None None None None None 1 1 None None None None None None 9 1106 None None None None None None 10 1107 None None None None None None None None None None Suite Location is None Suite Location is None 12

As soon as the only answer is incorrect (there is no more cells_from_range function in openpyxl) I suggest alternative way. I tried and it worked for my case:

Input is sheet and Cell. But if you need, it can be easily modified to accept string cell representation like 'A3'.

import openpyxl


def getValueWithMergeLookup(sheet, cell):
    idx = cell.coordinate
    for range_ in sheet.merged_cell_ranges:
        merged_cells = list(openpyxl.utils.rows_from_range(range_))
        for row in merged_cells:
            if idx in row:
                # If this is a merged cell,
                # return  the first cell of the merge range
                return sheet.cell(merged_cells[0][0]).value

    return sheet.cell(idx).value

Here's an approximation of the function that I use for this:

from openpyxl.cell import get_column_letter
from openpyxl.worksheet import cells_from_range

def getValueWithMergeLookup(sheet, col, row):
    idx = '{0}{1}'.format(get_column_letter(col), row)
    for range_ in sheet.merged_cell_ranges:
        cells = list(cells_from_range(range_))[0]
        if idx in cells:
            # If this is a merged cell, you can look up the value 
            # in the first cell of the merge range
            return sheet.cell(cells[0]).value

    return sheet.cell(row=row, column=col).value

The only really dicey bit there is where I extract the list of cells within the range to search against. That returns a generator, so I cast it to a list (because in doesn't work on generators, apparently), which yields a tuple containing a single list element, which I extract using the 0-index.

For my purposes, this is fast enough -- I use it by iterating the cells I want to test. If you wanted to make this more performant, it might be worthwhile to invert the loop, iterating the merge ranges as your outer loop, so you only have to do that conversion once.

from openpyxl import cell as xlcell, worksheet
def within_range(bounds: tuple, cell: xlcell) -> bool:
    column_start, row_start, column_end, row_end = bounds
    row = cell.row
    if row >= row_start and row <= row_end:
        column = cell.column
        if column >= column_start and column <= column_end:
            return True
    return False

def get_value_merged(sheet: worksheet, cell: xlcell) -> any:
    for merged in sheet.merged_cells:
        if within_range(merged.bounds, cell):
            return sheet.cell(merged.min_row, merged.min_col).value
    return cell.value

Should do it for current openpyxl version (2.6.3)

from openpyxl import * 
from openpyxl.utils import *

    def getValueWithMergeLookup(sheet, cell):
        if cell == None or sheet == None:
            return None
        for irange in sheet.merged_cell_ranges:
            min_col, min_row, max_col, max_row =range_boundaries(irange)
            if cell.row in range(min_row,max_row+1) and column_index_from_string(cell.column) in range(min_col,max_col+1):
                return sheet.cell(None,min_row,min_col).value
        return cell.value
