The behavior of the column width in Excel 2007 is the same as noted above. A rectangular area of cells can be merged into a single cell with the merge_cells() sheet method. I suppose other people must get better results than I just got, or they really don't care nearly as much as I do. I have filled a worksheet with some data and I'm trying to make column widths to assume their best fit, as in here. To unmerge cells, call the unmerge_cells() sheet method.

One day some determined soul might write a library for it (or it's already written, just not widely known), and then everyone can use that, but until then, I fully agree the benefit is not worth the development effort. XLSX file is the default file format for Microsoft Excel. All columns or rows resize to fit the data. It was born from lack of existing library to read/write natively from Python the Office Open XML format.

The openpyxl module has two built-in methods that can be used to perform these actions. Note: best_fit will attempt to calculate the correct column-width based on the longest value in each provided column. They are also used to determine the formatting for numbers.

Python provides the openpyxl module to work with excel files without even having to open the files. Even more pythonic way to set the width of all columns that works at least in openpyxl version 2.4.0: for column_cells in worksheet.columns: length = max (len (as_text (cell.value)) for cell in column_cells) worksheet.column_dimensions [column_cells [0].column].width = length. We can perform operations like read, write, draw charts, rename, add, delete, and style in the sheet. Security It appears the openpyxl developers have adopted that name as well. def column_letter(self): return get_column_letter(self.column_index) Example #2. The format of these columns is set to auto-wrap, so if the text is longer than what fits into the width, it will autowrap into several lines and the height of the row should adapt accordingly.

Today we got a quiz about function: "Take a text and a word as input and passes them to a function called search(); The search() function should return 'Word found' if the word is present in the text, or 'Word not found', if it's not." Here is my code: The solution will only be approximate. .more. http://stackoverflow.com/questions/17326973/is-there-a-way-to-auto-adjust-excel-column-widths-with-pandas-excelwriter, https://stackoverflow.com/a/32679806/3553923. Or is there some reason why not to do this? There are some other things to consider however: I think that will be acceptable (I guess it is the same that StyleFrame does and the best possible way of achieving it from within pandas). That last sentence is almost certainly true, but it's also almost irrelevant. ColumnDimension can get parameters as bestFit, auto_size (which is an alias of bestFit) and width . However, don't go overboard! That uses the openpyxl engine, so you can use that if you need this feature: http://styleframe.readthedocs.io. = ColumnDimension(conceptsWs, customWidth=True) dtsWs.column_dimensions[colLetter].width = hdr[1] writeCell(dtsWs, 1, i+1, hdr[0], hdr=True) # referenced taxonomies conceptsRow = 1 dtsRow = 3 .

How to write an empty function in Python pass statement? I had the same problem and have the following workaround which isn't perfect, but a good approximation: depending on the font I multiply the maximal length of a string in a column with a factor. However this isn't guaranteed to work for all fonts (works best with monospaced fonts). There will be cases where it doesn't work as expected and users will complain. Hello everyone! Let me preface by saying I only discovered that Stack Overflow question today, and I had never heard of StyleFrame before. I figured the `.auto_size` property would be the right thing to use, but setting that to True simply hides the column (and setting .hidden to False does not unhide it).
