How to read Excel Sheet Name?

KNIME Analytics Platform

Hello,
I have an excel file with the part of the Date reference (Year) in the Sheet name. I would like to read this to create a year column in my data table. Please could someone guide me on how to do this?

Hi @SeemaK

Here is how you can do it:

  1. You can create a flow variable from the path to the excel file in the Excel Reader (XLS) dialog
  2. Do some String manipulation using the String Manipulation (Variable) node.
  3. Use the new Flowvariable in the Constant Value Column node.

I created an example for this here: excel_year_extraction_to_column_example.knwf (10.8 KB)

Thank you for your response. I am trying to recreate the same with my files.
But not sure how you got the ‘Red dot’ output port on the Excel Reader. Excuse me for asking maybe the obvious! I am teaching myself to use KNIME.

Did you already go through our e-learing course?
There is a chapter on workflow control, which you can find here: https://www.knime.com/knime-introductory-course/chapter7
There is also a chapter about reading xls files, and a example workflow for this, which you can find here: KNIME Documentation

Cheers, Iris

Hi there!

If I’m not mistaken oole created a flow variable just by adding a name in a Excel Reader Node next to XLS_LOCATION on Flow variable tab. I’m I right?
