python xlsxwriter change row height for all rows in the sheet
Python xlsxwriter, change row height for all rows in the sheet, following is available but apply to single row
worksheet.set_row(0, 20) # Set the height of Row 1 to 20.
Want to change height of all the rows sheet.
Answer
To set the height of all rows in XlsxWriter, efficiently*, you can use the set_default_row() method:
worksheet.set_default_row(20)
(*) This is efficient because it uses an Excel optimisation to adjust the row heights with a single XML element. By contrast, using set_row() for each of the ~ 1 million rows would required 1 million XML elements and would lead to a very large file.
