'MergedCell' object attribute 'comment' is read-only
*Created originally on Bitbucket by [piotrdab_ (Piotr Dąbrowski)](https://bitbucket.org/%7Bbe52d5fe-4853-4882-89b3-ba2bbfb834a6%7D/)* I have a problem with opening some file. Trying to open it with `read_only=True` finishes without any problems, but I need to have an info whether a cell/row/column is hidden and currently don't see any other way than to load the file with `read_only=False`. I've stripped any unnecessary for this issue content from the file and attached as a `test_file.xlsx`. The file contain only one merged cell and does not open properly. ‌ ``` In [1]: from openpyxl import load_workbook In [2]: load_workbook('/home/piotr/Desktop/test_file.xlsx') --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-2-48edaf6f6504> in <module> ----> 1 load_workbook('/home/piotr/Desktop/test_file.xlsx') ~/miniconda3/envs/openpyxl/lib/python3.7/site-packages/openpyxl/reader/excel.py in load_workbook(filename, read_only, keep_vba, data_only, keep_links) 310 reader = ExcelReader(filename, read_only, keep_vba, 311 data_only, keep_links) --> 312 reader.read() 313 return reader.wb ~/miniconda3/envs/openpyxl/lib/python3.7/site-packages/openpyxl/reader/excel.py in read(self) 272 self.read_theme() 273 apply_stylesheet(self.archive, self.wb) --> 274 self.read_worksheets() 275 self.parser.assign_names() 276 if not self.read_only: ~/miniconda3/envs/openpyxl/lib/python3.7/site-packages/openpyxl/reader/excel.py in read_worksheets(self) 233 comment_sheet = CommentSheet.from_tree(fromstring(src)) 234 for ref, comment in comment_sheet.comments: --> 235 ws[ref].comment = comment 236 237 # preserve link to VML file if VBA AttributeError: 'MergedCell' object attribute 'comment' is read-only ``` ‌ ``` In [4]: openpyxl.__version__ Out[4]: '2.6.2' ``` *Attachments:* [test_file.xlsx](/uploads/6811cd4fd651a2d44cef662dd06dc3d7/test_file.xlsx)
