Filtering Through Excel in Ruby

To filter through an Excel file in Ruby, you can use the roo gem, which provides an interface to read data from various spreadsheet formats, including Excel. Here are the steps to filter through an Excel file in Ruby:

1. Install the roo gem by running the following command in your terminal: gem install roo

2. Require the roo gem in your Ruby script: ruby require 'roo'

3. Open the Excel file using the Roo::Excelx class: ruby excel = Roo::Excelx.new('path/to/excel/file.xlsx')

4. Select the sheet you want to filter: ruby excel.default_sheet = excel.sheets.first

5. Iterate over the rows in the sheet and filter based on your criteria: ruby excel.each_row_streaming do |row| # Filter rows based on your criteria if row[0] == 'Some Value' # Do something with the filtered row puts row.inspect end end

In this example, the code filters the rows based on the value in the first column. You can modify the condition to match your specific filtering criteria.

1. Close the Excel file: ruby excel.close

That's it! These steps will allow you to filter through an Excel file in Ruby using the roo gem.

Please note that the code provided is a general example, and you may need to modify it to fit your specific use case.
