One can import data from Excel ODBC source, but of course it is user's responsibility to ensure that the data are consistent. Each worksheet in the Excel workbook can be accessed as a table (for example, for Sheet1, you should type "select * from [Sheet1$]". The worksheet should have first row containing the column names, and the data rows should follow (the

Hello, I''m using the spreadsheet/excel gem to generate an excel sheet that I want user to be able to download it once it''s generated. Please take a look on the below code: @contacts=Contact.find(:all) if @contacts.size>0 file="#{Date.today}_Report.xls" workbook=Spreadsheet::Excel.new("#{RAILS_ROOT}/public/reports/#{file}")

I have a number of actions that use the spreadsheet/excel library to generate an Excel spreadsheet based on model data and send it to the user using the send_file method. For a while, I''ve been testing these methods with assert_response :success, and then checking the response headers to make sure the file at least looks like what I should be getting. But it occurred to me recently that

Hi all, There have been quite a few threads in the recent months pertaining to the ability to directly write native Excel (.xls) files from R. For example, exporting R matrices and/or data frames to an Excel file, with perhaps the ability to create multiple tabs (worksheets) within a single file, with one tab/sheet per R object. There exists the xlsReadWrite package on CRAN by Hans-Peter Suter,

Hello, I use a software that outputs the data in a form/dialect(?) of xml (I think its called "SpreadsheetML", see below for an excerpt). It allows (admittedly) easy import of such files into Excel. I would like, however, to import it directly into R. I am familiar how to do that with standard xml-files (mostly thanks to Duncan Temple Lang's help). But I haven't found the right

R version 2.13.1 OS X (or Windows) Colleagues, I received a number of files with a .xls extension. These files open in XL and, by all appearances, are XL files. However, it appears to me that the files are actually XML: > readLines(dir()[16])[1:10] [1] "<?xml version=\"1.0\"?>" [2] "<Workbook

Does anyone have experience with linux tools to parse the text from common non-text file formats for searching? I'm trying to use the kinosearch add-on for twiki which is fine as far as the search goes, but it takes forever to generate the index. It uses xpdf to extract strings from pdf's, antiword for .doc, and since it is perl, the Spreadsheet::ParseExcel module for .xls. Some

I?ve got an Excel workbook with about 30 worksheets. Each worksheet has 10000 rows of data over 30 columns. I?d like to read the data from each worksheet into a dataframe or matrix in R for processing. Normally, I use read.csv when interacting with Excel but I?d rather manipulate a multisheet workbook directly than set about splitting the original workbook and saving down each part as a csv.

I have gradually evolved a system such that these workbooks have become compendia of my
