Fastest ruby gem for reading Excel documents.

You should have Rust installed to build this gem. Tested with Ruby 3.2+.

Add this line to your application's Gemfile:

gem 'fastsheet'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fastsheet

Open a sheet:

require 'fastsheet'
sheet = Fastsheet::Sheet.new('path/to/sheet.xlsx')
# number of columns
sheet.width
# number of rows
sheet.height

Get rows or columns:

sheet.rows
sheet.row(42)
sheet.column(1)

Iterators (returns enumerator if no block given):

sheet.each_row { |r| ... }
sheet.each_column { |c| ... }
sheet.each_column.to_a # materialize columns if you need them all

That's all API for now. Dates and formula are currently returned as nil. Feel free to open an issue if you need more.
