Could forum members kindly help with the choice of an optimal tool-set?
Load a bunch of Excel spreadsheets and CSV files (preferably on the server side), combine the columns, parse and display the results of a query on the user's browser in an interactive html5 grid or similar?
I have looked at Logagent (lighter) and Logstash (heavy) for the backend (with some sort of batch ingestion), and Kibana for the front-end, but not sure if they are the right tools.
Display the data using Kibana on a portal (could be angular etc.) such that only those rows to be displayed which the user is allowed to see?
