External Python script using External Automation or Plugins

[steven.hess]

HI All,

I’m trying to create a Dataset into ignition from a excel macro based spreadsheet. I figured out the first part (converting the .xlsm to a .xlsx format) then reading the data into pandas. I was also able to create the dataframe using pandas and numpy using pycharm. However since ignition uses java instead of c we cannot use pandas or numpy in a native ignition platform.

I guess my main question would be would it be possible for Ignition to call the script from a external automation source such as Jenkins and then pull that data back to ignition? Or is there an easier approach to this?

Thanks
Steve

Take a look at this thread; we bundle a third-party library that understands Excel well enough to directly import files from it.

Copying an Excel file to a table's dataset

Got my paperwork done early, so here's a sample to read from an Excel file EDIT: Reworked a bit to work with both .xls and .xlsx files EDIT: Modified to properly cast data types EDIT: Added handler for formula cell types EDIT: Added parameters to optionally specify sheet, row, and column numbers Reading back a file created from my other example: def excelToDataSet(fileName, hasHeaders = False, sheetNum = 0, firstRow = None, lastRow = None, firstCol = None, lastCol = None): import org.apac…

Excellent, ill start working on the conversion from python to java. Ill let you know how it turns out here shortly
