Modifying

Adding Worksheets

workbook.worksheets[0].add_cell_obj(Cell.new(1,0,'blah')) #sets A2 to 'blah'

Changing Cells

workbook.worksheets[0][0][0].change_contents("", workbook.worksheets[0][0][0].formula) #sets A1 to empty string, preserves formula

Changing Fonts

workbook.worksheets[0].sheet_data[0][0].change_font_bold(true) #sets A1 to bold
workbook.worksheets[0].change_row_font_italics(0,true) #makes first row italicized
workbook.worksheets[0].change_column_font_name(0,'Courier') #makes first column have font Courier

# Possible "directions": top, bottom, left, right, diagonal
workbook.worksheets[0].sheet_data[0][0].change_border_top('thin') #sets A1 to have a top, thin border
workbook.worksheets[0].change_row_border_left(0, 'hairline') #sets first row to have a left, hairline border
workbook.worksheets[0].change_column_border_diagonal(0, 'medium') #sets first column to have diagonal, medium border

Changing Alignment

Horizontal

center, distributed, justify, left, right

workbook.worksheets[0].sheet_data[0][0].change_horizontal_alignment('center') #sets A1 to be centered
workbook.worksheets[0].change_row_horizontal_alignment(0,'justify') #sets first row to be justified

Merging Cells

workbook.worksheets[0].merge_cells(0,0,1,1) #merges A1:B2

Insert Row

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

workbook.worksheets[0].insert_row(1)

Insert Column

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

workbook.worksheets[0].insert_column(1)

Delete Row

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

workbook.worksheets[0].delete_row(1)

Delete Column

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

workbook.worksheets[0].delete_column(1)

Insert Cell

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

workbook.worksheets[0].insert_cell(0,0,"blah",formula=nil,:right) #inserts cell at A1, shifts cells in first row right
workbook.worksheets[0].insert_cell(0,0,"blah",formula=nil,:down) #inserts cell at A1, shifts cells in first column down
workbook.worksheets[0].insert_cell(0,0,"blah") #inserts cell at A1, shifts nothing

Delete Cell

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

workbook.worksheets[0].delete_cell(0,0,:left) #deletes A1, shifts contents of first row left
workbook.worksheets[0].delete_cell(0,0,:up) #deletes A1, shifts contents of first column up
workbook.worksheets[0].delete_cell(0,0) #deletes A1, does not shift cells

Writing

workbook.write("path/to/desired/Excel/file.xlsx")

Miscellaneous

Cell.convert_to_cell(0,0) == 'A1' #converts row and column index to Excel-style index
Parser.convert_to_index('A1') == [0,0] #converts Excel-style index to row and column index

Contributing to rubyXL

• 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.
