This gem supports operating on xlsx files (Open XML format). While it is capable of properly parsing the entire OOXML structure, its current main emphasis is on reading files produced by MS Excel, making minor modifications to them and saving them to be opened again, while preserving as much of the structure as possible.
Please note that proprietary binary xls format is not supported.
gem install rubyXL
require 'rubyXL' # Assuming rubygems is already required
workbook = RubyXL::Parser.parse("path/to/Excel/file.xlsx")
workbook = RubyXL::Workbook.new
workbook.worksheets[0] # Returns first worksheet workbook[0] # Returns first worksheet workbook['Sheet1'] # Finds and returns worksheet titled "Sheet1"
worksheet = workbook[0] worksheet.extract_data # Produces a simple rectangular array that consists only of cell values (rather than the Cell objects)
worksheet = workbook[0] worksheet.sheet_data[0] # Returns first row of the worksheet worksheet[0] # Returns first row of the worksheet
worksheet = workbook[0] worksheet.sheet_data[0][0] # Returns cell A1 in the worksheet worksheet[0][0] # Returns cell A1 in the worksheet
cell = workbook[0][0][0] cell.is_struckthrough # Returns +true+ if the cell is struckthrough, other boolean properties have same syntax cell.font_name cell.font_size cell.font_color cell.fill_color cell.horizontal_alignment cell.vertical_alignment cell.border_top
Please note: these methods are being phased out in favor of the OOXML object model.

This method will insert a row at specified index, pushing all rows below it down. It also copies styles from row above.
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted rows
worksheet.insert_row(1)
This method will insert a column at specified index, pushing all columns to the right of it one to the right. It also copies styles from column to the left
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted columns
worksheet.insert_column(1)
This method will delete a row at specified index, pushing all rows below it up.
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted rows
worksheet.delete_row(1)
This method will delete a column at specified index, pushing all columns to the right of it left.
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted columns
worksheet.delete_column(1)
This method will insert a cell at specified position. It takes a :right or :down option, to shift cells either left or down upon inserting (nil means replacing the cell)
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted cells
worksheet.insert_cell(0, 0, "blah", formula = nil, :right) # Inserts cell at A1, shifts cells in first row right worksheet.insert_cell(0, 0, "blah", formula = nil, :down) # Inserts cell at A1, shifts cells in first column down worksheet.insert_cell(0, 0, "blah") # Inserts cell at A1, shifts nothing
This method will delete a cell at specified position. It takes a :left or :up option, to shift cells either up or left upon deletion (nil means simply deleting the cell contents)
WARNING: Use of this method WILL break formulas referencing cells which have been moved, as the formulas do not adapt to the shifted cells
worksheet.delete_cell(0, 0, :left) # Deletes A1, shifts contents of first row left worksheet.delete_cell(0, 0, :up) # Deletes A1, shifts contents of first column up worksheet.delete_cell(0, 0) # Deletes A1, does not shift cells
workbook.write("path/to/desired/Excel/file.xlsx")
The gem can provide StringIO object containing the resulting xlsx file, eliminating the need to save it to disk first. This capability comes in handy for web servers.
workbook.stream
Reference.ind2ref(0,0) == 'A1' # Converts row and column index to Excel-style cell reference Reference.ref2ind('A1') == [0, 0] # Converts Excel-style cell reference to row and column index
Take a look at the files in spec/lib/ for rspecs on most methods
-
Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
-
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
-
Fork the project
-
Start a feature/bugfix branch
-
Commit and push until you are happy with your contribution
-
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
