# node-red-csv-parser

Simple Node-RED flow for uploading/deleting CSV files from dashboard and converting it to JSON objects.

# Requirements

Node-RED >= v3.0

  Palletes:

    - node-red-contrib-dashboard [LINK](https://flows.nodered.org/node/node-red-dashboard)

# Description

Simple flow for reading and saving files into preselected directory.

Files are read and content is displayed in a template node.


Dashboard gives an option to 'activate' detected datapoints, which means to save them into 'datapoints' object -

a global variable.


This parser has been used to read CSV files generated by WAGO EDM software to then read listed MODBUS registers.


# Instructions

- Flow is preset to save files into './files' directory (directory is created if it doesn't exist)

- Flow is preset to accept '.csv' files only

- Template node is preset to display elements of detected objects:

    - ID

    - Name

    - Description

    - Unit

    - Datatype

    - Address

    - FC

  

 > 
As mentioned, this parser has been used to read a list of MODBUS registers, but if intended use is different, simply just change column titles and element references inside template node.
