xlsx |
|
==== |
|
|
|
Pulls ExcelX data from .xlsx files into a hash of arrays keyed by the headers. First row is assumed to be the header row. |
|
|
|
The ``xlsx`` method is a member of ``Squib::Deck``, but it is also available outside of the Deck DSL with ``Squib.xlsx()``. This allows a construction like:: |
|
|
|
data = Squib.xlsx file: 'data.xlsx' |
|
Squib::Deck.new(cards: data['name'].size) do |
|
end |
|
|
|
Options |
|
------- |
|
|
|
file |
|
default: ``'deck.xlsx'`` |
|
|
|
the xlsx-formatted file to open. Opens relative to the current directory. |
|
|
|
sheet |
|
default: ``0`` |
|
|
|
The zero-based index of the sheet from which to read. |
|
|
|
strip |
|
default: ``true`` |
|
|
|
When ``true``, strips leading and trailing whitespace on values and headers |
|
|
|
explode |
|
default: ``'qty'`` |
|
|
|
Quantity explosion will be applied to the column this name. For example, rows in the csv with a ``'qty'`` of 3 will be duplicated 3 times. |
|
|
|
Individual Pre-processing |
|
------------------------- |
|
|
|
The ``xlsx`` method also takes in a block that will be executed for each cell in your data. This is useful for processing individual cells, like putting a dollar sign in front of dollars, or converting from a float to an integer. The value of the block will be what is assigned to that cell. For example:: |
|
|
|
resource_data = Squib.xlsx(file: 'sample.xlsx') do |header, value| |
|
case header |
|
when 'Cost' |
|
"$#{value}k" # e.g. "3" becomes "$3k" |
|
else |
|
value # always return the original value if you didn't do anything to it |
|
end |
|
end |
|
|
