How do you interface back and forth with excel spreadsheets? I want to have a live interface with an Ignition app.
You could use my newly released module RWS New module - RWS - Restful Web Services , from PRAMANJ Technologies to display data in a table in HTML page which can be imported in an EXCEL using import data from a web page option to display it in your EXCEL. There are a lot of tutorials available in the YouTube which show how to import data in EXCEL from an HTML table. You could do a google search to see the videos. Or you could use Microsoft’s EXCEL web services to display an EXCEL sheet in a browser and interact with it.
Let me know your requirements perhaps I can build a solution for you.
