#encoding: utf-8
require ‘spreadsheet’

folder = “\\\\server100\\folder1\\folder2″
file = folder << "\\" << "olé-olé-file.xls"
Spreadsheet.client_encoding = 'UTF-8'
Spreadsheet.open(file) do |book|
puts "sheets: #{book.worksheets.size}"
sheet = book.worksheet(0)
puts "First sheet name: #{sheet.name}"
end

But when I pass the same file name from a variable, it doe not work:

require 'spreadsheet'

folder = "\\\\server100\\folder1\\folder2"
pattern = "ole-olé-*.xls"
Dir.chdir(folder)
source_files = Dir.glob(pattern)
recent_file = source_files.max_by { |f1| File.mtime(f1) }
file = folder << "\\" << recent_file

Spreadsheet.open(file) do |book|
puts "sheets: #{book.worksheets.size}"
sheet = book.worksheet(0)
puts "First sheet name: #{sheet.name}"
end

The error I get is the following:

C:/Ruby193/lib/ruby/gems/1.9.1/gems/spreadsheet-0.6.8/lib/spreadsheet/excel/reader.rb:1172:in `setup': undefined method `read' for false:FalseClass (NoMeth

It happened on Windows XP SP3 box, Ruby 1.9.3, spreadsheet 0.6.8
Thank you

The fix was to delete the file prior to writing.

I have added a Gist here [1] for anyone else to have a look at for similar issues.

Hope it helps others.

Each created XLS file only has one worksheet, and after opening I am simply appending another row then writing the file.

I’ll do a bit more digging, and post on the group if necessary.

Thanks

I want to use Spreadsheet to collate a bunch of sheets, so that I copy rows from x number of sheets and dump them into newly created sheets based on certain criteria.

Opening, reading, extracting the rows, and the initial creation of the ‘dump’ sheets is not a problem (all nice and easy), but when Spreadsheet opens a sheet created with Spreadsheet and inserts a row, then writes the file, I am no longer able to open the spreadsheet with either excel or open office – when I try I get an invalid file format message.

I don’t get any errors when running my cukes (apart from trying to open the files manually later), but when I run the program from the cmd line, I get the following runtime error:

/.rvm/gems/ruby-1.9.2-p290@account_manager/gems/spreadsheet-0.6.5.7/lib/spreadsheet/excel/workbook.rb:60:in `block in biff_version’: Unkown BIFF_VERSION ” (RuntimeError)

If I start an IRB session and try to open the sheet with Spreadsheet, I get the same error.

I presume I am missing something when it comes to writing the file a second time?

Any ideas?

Many Thanks

Paul
