Ironpython write to Excel

I am trying to write data from Revit to Excel with RevitPythonShell.

So far I have collected all data in a zipped list and made an enumerated for loop to write the data to the corresponding rows and columns as following:

for index, data in enumerate(wall_zipped_list):
    for count, parameters in enumerate(data):
        wall_cell = worksheet_wanden.Range[(str(column_list[count]))+str(index+5)]      
        wall_cell.Value2 = data[count]

This is incredibly slow because the loop is calling Value2 everytime. A Revit model containing about 800 walls takes 2 minutes to write to Excel. So I tried a different method using a dictionary. 

for k , v in data_dict.iteritems():
    #print k, v[0]
    worksheet_wanden.Range["A"+str(count)].Value2 = k
    worksheet_wanden.Range["B"+str(count)].Value2 = v[0]
    worksheet_wanden.Range["C"+str(count)].Value2 = v[1]
    worksheet_wanden.Range["D"+str(count)].Value2 = v[2]
    worksheet_wanden.Range["E"+str(count)].Value2 = v[3]
    worksheet_wanden.Range["F"+str(count)].Value2 = v[4]
    worksheet_wanden.Range["G"+str(count)].Value2 = v[5]
    worksheet_wanden.Range["H"+str(count)].Value2 = v[6]
    worksheet_wanden.Range["I"+str(count)].Value2 = v[7]
    worksheet_wanden.Range["J"+str(count)].Value2 = v[8]
    worksheet_wanden.Range["K"+str(count)].Value2 = v[9]
    count += 1

This method is already a lot quicker. This takes about 20 seconds to fill about 800 rows with 10 columns in Excel. Am I missing some IronPython functionality which you can write dictionary or lists to Excel rows or columns?

I also looked at installing 3d party modules. But this is not really an option since RevitPythonShell usising IronPython 2.7.3 and I can't get pip install to work.

Thanks in advance.

Is it maybe faster to write to csv first in IronPython and then import it some way into excel?

If you're referring to the Cells notation that you can use in VB, I don't know why it does not work, but you could create a definition:

def Cells(a,b):
    return str(chr(a+96) + str(b))

Now you could call something like:

x1range = ws.Range(Cells(1,1),Cells(5,10))

and it will work the same. That is what I do.

It works

i = 0 

xlrange_revit_type = worksheet_data.Range["C2:C" + str(len(revit_type_list)+1)]
a = Array.CreateInstance(object,len(revit_type_list), 3) 

while i < len(revit_type_list):
    a[i,0] = revit_type_list[i]
    i += 1

xlrange_revit_type.Value2 = a

Is it possible to install a 3d party module like xlwt for RevitPythonShell? I can't find any documentation.

This is more of a question on .NET/Excel interop. I think, based on this SO question you should be able to assign an array to a range.

That is, your current range is just one cell. You could try creating a 2d System.Array and assign it to the range... I tried it out here:

``` import clr clr.AddReference("Microsoft.Office.Interop.Excel")

import Microsoft.Office.Interop.Excel as Excel excel = Excel.ApplicationClass() excel.Visible = True # makes the Excel application visible to the user workbook = excel.Workbooks.Add() worksheet = workbook.Worksheets.Add()

from System import Array xlrange = worksheet.Range["A1:c3"]

a = Array.CreateInstance(object, 3, 3) i = 0 for row in range(3): for column in range(3): a[row, column] = i i += 1

xlrange.Value2 = a ```

This produces a result like this:

More information on IronPython and Excel can be found here: http://www.ironpython.info/index.php?title=Interacting_with_Excel

You could try installing the xlwt module and use that - avoiding COM interop.
