  • Reading excel files with xlrd

    - by snurre
    I'm having problems reading .xls files written by a Perl script which I have no control over. The files contain some formatting and line breaks within cells. filename = '/home/shared/testfile.xls' book = xlrd.open_workbook(filename) sheet = book.sheet_by_index(0) for rowIndex in xrange(1, sheet.nrows): row = sheet.row(rowIndex) This is throwing the following error: _locate_stream(Workbook): seen 0 5 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 20 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 172480= 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 172500 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 3 2 172520 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 173840= 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 173860 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 1 1 173880 1 1 1 1 1 1 1 1 Traceback (most recent call last): File "/home/shared/xlrdtest.py", line 5, in <module> book = xlrd.open_workbook(filename) File "/usr/local/lib/python2.7/site-packages/xlrd/__init__.py", line 443, in open_workbook ragged_rows=ragged_rows, File "/usr/local/lib/python2.7/site-packages/xlrd/book.py", line 84, in open_workbook_xls ragged_rows=ragged_rows, File "/usr/local/lib/python2.7/site-packages/xlrd/book.py", line 616, in biff2_8_load self.mem, self.base, self.stream_len = cd.locate_named_stream(qname) File "/usr/local/lib/python2.7/site-packages/xlrd/compdoc.py", line 393, in locate_named_stream d.tot_size, qname, d.DID+6) File "/usr/local/lib/python2.7/site-packages/xlrd/compdoc.py", line 421, in _locate_stream raise CompDocError("%s corruption: seen[%d] == %d" % (qname, s, self.seen[s])) xlrd.compdoc.CompDocError: Workbook corruption: seen[2] == 4 I'm not able to find any info about CompDocError or Workbook corruption, even less the seen[2] == 4 part.

  • Reading numeric Excel data as text using xlrd in Python

    - by Brian
    Hi guys, I am trying to read in an Excel file using xlrd, and I am wondering if there is a way to ignore the cell formatting used in Excel file, and just import all data as text? Here is the code I am using for far: import xlrd xls_file = 'xltest.xls' xls_workbook = xlrd.open_workbook(xls_file) xls_sheet = xls_workbook.sheet_by_index(0) raw_data = [['']*xls_sheet.ncols for _ in range(xls_sheet.nrows)] raw_str = '' feild_delim = ',' text_delim = '"' for rnum in range(xls_sheet.nrows): for cnum in range(xls_sheet.ncols): raw_data[rnum][cnum] = str(xls_sheet.cell(rnum,cnum).value) for rnum in range(len(raw_data)): for cnum in range(len(raw_data[rnum])): if (cnum == len(raw_data[rnum]) - 1): feild_delim = '\n' else: feild_delim = ',' raw_str += text_delim + raw_data[rnum][cnum] + text_delim + feild_delim final_csv = open('FINAL.csv', 'w') final_csv.write(raw_str) final_csv.close() This code is functional, but there are certain fields, such as a zip code, that are imported as numbers, so they have the decimal zero suffix. For example, is there is a zip code of '79854' in the Excel file, it will be imported as '79854.0'. I have tried finding a solution in this xlrd spec, but was unsuccessful.

  • Are xlrd and xlwt compatible?

    - by Leo
    I'm trying to create a workbook with python and I need to test the values of different cells to fill it but I'm having some troubles. I use xlrd and xlwt to create and edit the excel file. I've made a little example of my problem and I don't understand why it's not working. import xlwt import xlrd wb = xlwt.Workbook() ws = wb.add_sheet('Test') ws.write(0,0,"ah") cell = ws.cell(0,0) # AttributeError: 'Worksheet' object has no attribute 'cell' print cell.value I had taken for granted that xlrd and xlwt have shared classes which can interact with each other but it doesn't seem to be the case. How do I get the cell value of an open Worksheet object?

  • Why is win32com so much slower than xlrd?

    - by Josh
    I have the same code, written using win32com and xlrd. xlrd preforms the algorithm in less than a second, while win32com takes minutes. Here is the win32com: def makeDict(ws): """makes dict with key as header name, value as tuple of column begin and column end (inclusive)""" wsHeaders = {} # key is header name, value is column begin and end inclusive for cnum in xrange(9, find_last_col(ws)): if ws.Cells(7, cnum).Value: wsHeaders[str(ws.Cells(7, cnum).Value)] = (cnum, find_last_col(ws)) for cend in xrange(cnum + 1, find_last_col(ws)): #finds end column if ws.Cells(7, cend).Value: wsHeaders[str(ws.Cells(7, cnum).Value)] = (cnum, cend - 1) break return wsHeaders And the xlrd def makeDict(ws): """makes dict with key as header name, value as tuple of column begin and column end (inclusive)""" wsHeaders = {} # key is header name, value is column begin and end inclusive for cnum in xrange(8, ws.ncols): if ws.cell_value(6, cnum): wsHeaders[str(ws.cell_value(6, cnum))] = (cnum, ws.ncols) for cend in xrange(cnum + 1, ws.ncols):#finds end column if ws.cell_value(6, cend): wsHeaders[str(ws.cell_value(6, cnum))] = (cnum, cend - 1) break return wsHeaders

  • pivots using pyExcelerator/xlrd

    - by Raj N
    How can I go about creating a sheet with a pivot table using python libs like pyExcelerator / xlrd? I need to generate a daily report that has a pivot table to summarize data on other sheets. One option would be to have a blank template that I copy and populate with the data. In this case, is there a way to refresh the pivot from code? Any other suggestions?

  • writing to existing workbook using xlwt

    - by Raj N
    I am unable to find examples where xlwt is used to write into existing files. I have a existing xls file that I need to write to. When I use xlrd to read the file, I cant seem to figure out how to transform the "Book" type returned into a xlwt.Workbook. I would appreciate if someone can point me to an example.

    - by David542
    I have a user uploading a file to a website and I need to parse the spreadsheet.

Thank you. For reference, this is how I open the file in the shell >>> import xlrd >>> xlrd.open_workbook('/Users/me/dave_example.xls') <xlrd.Book object at 0x10d9f7390>

  • Converting excel files to python to frequency

    - by Jacob
    Essentially I've got an excel files with voltage in the first column, and time in the second. I want to find the period of the voltages, as it returns a graph of voltage in y axis and time in x axis with a periodicity, looking similar to a sine function. To find the frequency I have uploaded my excel file to python as I think this will make it easier- there may be something I've missed that will simplify this. So far in python I have: import xlrd import numpy as N import numpy.fft as F import matplotlib.pyplot as P wb = xlrd.open_workbook('temp7.xls') #LOADING EXCEL FILE wb.sheet_names() sh = wb.sheet_by_index(0) first_column = sh.col_values(1) #VALUES FROM EXCEL second_column = sh.col_values(2) #VALUES FROM EXCEL Now how do I find the frequency from this? Huge thanks to anyone who can help! Jacob

    - by locojay
    Hi I have 1000 encrypted workbooks which I would like to decrypt by providing a pwd. I could not find a decrypt method under apache poi or python's xlrd module. Does anyone know a library which could handle this (wbc.decrypt(pwd)). I would prefer a lib i could you use from a unix box. Thanks

  • Best tools to create valid XML files from an Excel file

    - by systempuntoout
    I need to create a script that extracts some data from a complex Excel 2003 file (with multiple Sheets and different tables inside a single sheet) and produces different XML files that need to be validated against a given XSD file. My preferred language is Python; to create and validate XML files i would go with lxml. What do you suggest for parsing XSL files? Is xlrd the right tool to use for complex Excel files? Or do i need to convert all the sheets in CSV manually, and read files line by line, splitting and getting data? I accept C#, VB6 suggestions too.

  • Excel Regex, or export to Python? ; "Vlookup" in Python?

    - by victorhooi
    heya, We have an Excel file with a worksheet containing people records. 1. Phone Number Sanitation One of the fields is a phone number field, which contains phone numbers in the format e.g.: +XX(Y)ZZZZ-ZZZZ (where X, Y and Z are integers). There are also some records which have less digits, e.g.: +XX(Y)ZZZ-ZZZZ And others with really screwed up formats: +XX(Y)ZZZZ-ZZZZ / ZZZZ or: ZZZZZZZZ We need to sanitise these all into the format: 0YZZZZZZZZ (or OYZZZZZZ with those with less digits). 2. Fill in Supervisor Details Each person also has a supervisor, given as an numeric ID. We need to do a lookup to get the name and email address of that supervisor, and add it to the line. This lookup will be firstly on the same worksheet (i.e. searching itself), and it can then fallback to another workbook with more people. 3. Approach? For the first issue, I was thinking of using regex in Excel/VBA somehow, to do the parsing. My Excel-fu isn't the best, but I suppose I can learn...lol. Any particular points on this one? However, would I be better off exporting the XLS to a CSV (e.g. using xlrd), then using Python to fix up the phone numbers? For the second approach, I was thinking of just using vlookups in Excel, to pull in the data, and somehow, having it fall through, first on searching itself, then on the external workbook, then just putting in error text. Not sure how to do that last part. However, if I do happen to choose to export to CSV and do it in Python, what's an efficient way of doing the vlookup? (Should I convert to a dict, or just iterate? Or is there a better, or more idiomatic way?) Cheers, Victor
