I am trying to read an Excel spreadsheet file with Ruby, but it is not reading the content of the file.
This is my script
book = Spreadsheet.open 'myexcel.xls';
sheet1 = book.worksheet 0
sheet1.each do |row|
puts row.inspect ;
puts row.format 2;
puts row[1];
exit;
end
It is giving me the following:
[DEPRECATED] By requiring 'parseexcel', 'parseexcel/parseexcel' and/or
'parseexcel/parser' you are loading a Compatibility layer which
provides a drop-in replacement for the ParseExcel library. This
code makes the reading of Spreadsheet documents less efficient and
will be removed in Spreadsheet version 1.0.0
#<Spreadsheet::Excel::Row:0xffffffdbc3e0d2 @worksheet=#<Spreadsheet::Excel::Worksheet:0xb79b8fe0> @outline_level=0 @idx=0 @hidden=false @height= @default_format= @formats= []>
#<Spreadsheet::Format:0xb79bc8ac>
nil
I need to get the actual content of file. What am I doing wrong?
It looks like row
, whose class is Spreadsheet::Excel::Row
is effectively an Excel Range
and that it either includes Enumerable or at least exposes some enumerable behaviours, #each
, for example.
So you might rewrite your script something like this:
require 'spreadsheet'
book = Spreadsheet.open('myexcel.xls')
sheet1 = book.worksheet('Sheet1') # can use an index or worksheet name
sheet1.each do |row|
break if row[0].nil? # if first cell empty
puts row.join(',') # looks like it calls "to_s" on each cell's Value
end
Note that I've parenthesised arguments, which is generally advisable these days, and removed the semi-colons, which are not necessary unless you're writing multiple statement on a line (which you should rarely - if ever - do).
It's probably a hangover from a larger script, but I'll point out that in the code given the book
and sheet1
variables aren't really needed, and that Spreadsheet#open
takes a block, so a more idiomatic Ruby version might be something like this:
require 'spreadsheet'
Spreadsheet.open('MyTestSheet.xls') do |book|
book.worksheet('Sheet1').each do |row|
break if row[0].nil?
puts row.join(',')
end
end
