xlrd

I am not quite sure how to use the following function: xlrd.xldate_as_tuple for the following data xldate:39274.0 xldate:39839.0 Could someone please give me an example on usage of the function for the data? msw Quoth the documentation : Dates in Excel spreadsheets In reality, there are no such things. What you have are floating point numbers and pious hope. There are several problems with Excel dates: (1) Dates are not stored as a separate data type; they are stored as floating point numbers and you have to rely on (a) the "number format" applied to them in Excel and/or (b) knowing which

I want to create a dictionary from the values, i get from excel cells, My code is below, wb = xlrd.open_workbook('foo.xls') sh = wb.sheet_by_index(2) for i in range(138): cell_value_class = sh.cell(i,2).value cell_value_id = sh.cell(i,0).value and I want to create a dictionary, like below, that consists of the values coming from the excel cells; {'class1': 1, 'class2': 3, 'class3': 4, 'classN':N} Any idea on how I can create this dictionary? d = {} wb = xlrd.open_workbook('foo.xls') sh = wb.sheet_by_index(2) for i in range(138): cell_value_class = sh.cell(i,2).value cell_value_id = sh.cell(i,0

I'm looking for the best approach for inserting a row into a spreadsheet using openpyxl. Effectively, I have a spreadsheet (Excel 2007) which has a header row, followed by (at most) a few thousand rows of data. I'm looking to insert the row as the first row of actual data, so after the header. My understanding is that the append function is suitable for adding content to the end of the file. Reading the documentation for both openpyxl and xlrd (and xlwt), I can't find any clear cut ways of doing this, beyond looping through the content manually and inserting into a new sheet (after inserting

I am trying to create an Excel workbook where I can auto-set, or auto-adjust the widths of the columns before saving the workbook. I have been reading the Python-Excel tutorial in hopes of finding some functions in xlwt that emulate xlrd ones (such as sheet_names() , cellname(row, col) , cell_type , cell_value , and so on...) For example, suppose I have the following: from xlwt import Workbook wb = Workbook() sh1 = wb.add_sheet('sheet1' , cell_overwrite_ok = True) sh2 = wb.get_sheet(0) wb.get_sheet(0) is similar to the rb.sheet_by_index(0) function offered in xlrd, except that the former

In the documentation for xlrd and xlwt I have learned the following: How to read from existing work-books/sheets: from xlrd import open_workbook wb = open_workbook("ex.xls") s = wb.sheet_by_index(0) print s.cell(0,0).value #Prints contents of cell at location a1 in the first sheet in the document called ex.xls How to create new work-books/sheets: from xlwt import Workbook wb = Workbook() Sheet1 = wb.add_sheet('Sheet1') Sheet1.write(0,0,'Hello') wb.save('ex.xls') #Creates a document called ex.xls with a worksheet called "Sheet1" and writes "Hello" to the cell located at a1 What I want to do now
