Dyntools Overwrite Excel Sheet

Hello,

I am using dyntools to output data to excel.

dyntools.CHNF.xlsout(xlsresult, channels=[], show=False, xlsfile=xlsoutput, outfile=outfile, overwritesheet = True)

This is the code I am using, I believe that overwritesheet = True should overwite sheet1 every time I run the script.

I currently need to delete the old excel sheet every time I re run my script or else the excel workbook will create new sheets of the same data, which causes the file to become huge.

What should I do?

Thanks

In v.33.12, the overwritesheet setting works as expected. The following is the code I used:

   try: 
     chnfobj.xlsout(channels=mychannels, 
                    outfile=filei,
                    xlsfile=XLSfile,
                    sheet=sheetname,
                    overwritesheet = True,
                    show=False 
                    )
   except:
     print '\n ERROR: Exporting Channels to %s Excel file, sheet %s failed.'%(XLSfile,sheetname)

I found that even if you set overwritesheet = True, it does not always overwrite it. In fact, I have encountered multiple cases where I wanted it to be overwritten but new sheets were added to the workbook instead. Could be a bug.

I have the following problem Dyntools does not extract data from file out

** LINES PER PAGE for FILE OUTPUT set to 60

Output completed Traceback (most recent call last): File "C:\0-C\0-Simulaciones\Caso\Simulación.py", line 227, in <module> datosexcel = dyntools.CHNF(archivoout + '.out') File ".\dyntools.py", line 1023, in init File ".\dyntools.py", line 351, in outextractdata File ".\dyntools.py", line 321, in outextractid

Couldn't open Python file: C:\0-C\0-Simulaciones\Caso\Simulación.py

Hello, I don't know how to solve this problem, but my opinion is that you should never use orthographic accent in Python even in comments or files names.

if you also have lots of sheets you could delete a folder and remake it instead of each sheet,

if os.path.exists(PathDir + r"\sheets"):
    shutil.rmtree(PathDir + r"\sheets")
    os.makedirs(PathDir + r"\sheets")

Tried this as a comment but no formatting was available. Sorry if you got spammed with notifications of me changing the comment a bunch

I think that this overwritesheet = true option will overwrite latest sheet if it is called more than once during simulation.

In my case, I am re running the script rather than using the dyntools command more than once in the same script.

To overcome this, I check for and delete existing excel file in directory by adding the following code just before using dyntools.CHNF.xlsout(..)

if os.path.exists(xlsoutput):
   try:
      os.remove(xlsoutput)
   except WindowsError:
      print 'file is open'
