Re: Excel and Ruby

~ *****With regard to your question about what I am trying to do... The
first
objective of my program is to bring me up to speed using Ruby program to
automate the extraction of data from Excel spreadsheets. Once I have got
that working then I will extract data from a large spreadsheet covering
levy payments by occupants in a retirement village and then use Ruby to
print out letters to individual occupants who are wanting to reconcile
their payments.  This will then require using Ruby to print reports.
Examples of doing this seems pretty scarce.*****~

As far as extracting the data from an excel sheet, I'm assuming Names and
Levy payments and inserting into a report. What kind of report are we
talking about? Is it just text? A crystal report?

for i in 1..100 do
# Lets iterate of each of these values into an array
worksheet.Range("A#{i}").each do |cella|
worksheet.Range("B#{i}").each do |cellb|
#This could also be done without a loop by simply calling the range of cells
worksheet.Range("A1:A100").each do |cella|
worksheet.Range("B1:B100").each do |cellb|
=beginAnd make sure we are talking about text and values here. Assuming of
course cell a is names and cell b is a value or number. Value has to to do
with integers and floats. Integars are whole numbers where as floats extend
with past the decimal. 1 = integer 2.22 = float
=end

cellcontentsA = cella.text
cellcontentsB = callb.value

puts cellvaluea
puts cellvalueb

Array's come with their own special methods and you can see what the methods
are by typing in Array.methods Lots of cool toys in there :) <3 Ruby


Hope this explains it better :) There are so many ways to get the same
results, it's fun to look over new things and condense it to the most simple
form. This is not the most simple form but for learning purposes II hope it
does a good job explaining each element of the code for you.
If everything works out the way you want to let me know and we can get on to
making the Mailing letters and printing them out. Can do this in many ways
in either word, a text file, simply e-mail automatically. You name it. It's
there.
