Openpyxl currently supports the reading and writing of comment text only.
Formatting information is lost. Comment dimensions are lost upon reading,
but can be written. Comments are not currently supported if
read_only=True is used.
Comments have a text attribute and an author attribute, which must both be set
>>> fromopenpyxlimportWorkbook>>> fromopenpyxl.commentsimportComment>>> wb=Workbook()>>> ws=wb.active>>> comment=ws["A1"].comment>>> comment=Comment('This is the comment text','Comment Author')>>> comment.text'This is the comment text'>>> comment.author'Comment Author'
If you assign the same comment to multiple cells then openpyxl will automatically create copies
Comments present in a workbook when loaded are stored in the comment
attribute of their respective cells automatically. Formatting information
such as font size, bold and italics are lost, as are the original dimensions
and position of the comment’s container box.
Comments remaining in a workbook when it is saved are automatically saved to
the workbook file.
Comment dimensions can be specified for write-only. Comment dimension are
in pixels.
