Download Workflow

This workflow takes a spreadsheet exported as a tab delimited file, such as an Excel spreadsheet. The style is expected as a matrix of data with the first row containing the column names and the first column containing the row names (see below). The top left cell is discarded.

The workflow outputs three lists. A list of column names, a list of row names, and a two deep list of data points. The first list is a list of the rows and the sublist is a list of values of the cells from the columns.

	A	B	C	D
p	1	2	3	4
q	5	6	7	8
r	9	10	11	12
s	13	14	15	16

Inputs (1)

Name	Description
TabDelimitedExcelFile

Processors (6)

Name	Type	Description
SplitColumnNamesIntoList	local	Splits the header row of the Excel Sheet by tab
SplitRows	local	Splits the Excel Spreadsheet by newlines, giving a list of strings, each string being a row
MakeColumnNameList	beanshell	For some reason, the previous processor returns a list of lists. This beanshell simply converts it back to a 1-deep list.
SplitDataRows	beanshell	Separates the header row from the rest of the rows for separate processing
SplitDataPoints	local	Splits each row from the excel spreadsheet by tab regex. Each iteration produces a list of the values from the cells of each row. Overall a list of lists is produced.
SplitRowNames	beanshell	Filters out the first element of each row to build the list of row names and the 2-deel list of data points by row
