TagProps Transformer

This tool transforms tag properties in JSON files by replacing the first value in the tagProps array with a path based on the element's name, an MCM number, and a device type.

Usage

python tag_transformer.py <input_file.json> <mcm_number> [device_type]

Example:

python tag_transformer.py sample_input.json 07 Conveyor

This will:

1. Read the input JSON file (sample_input.json)
2. For each element in the JSON, replace only the first value in the tagProps array with System/MCM07/Conveyor/[ElementName]
3. Output the transformed JSON to the console

Auto Device Type Detection

If you don't specify a device type, the script will automatically determine the device type based on the element name:

• If the name contains EPC followed by "End" (e.g., EPCEnd, EPC_End, EPC1_End, EPC2_End_1), the device type will be EPC_End
• If the name contains EPC followed by a number (e.g., EPC1, EPC2, EPC_1), the device type will be EPC
• If the name contains EPC followed by "Line" (e.g., EPCLine, EPC_Line), the device type will be EPC_Line
• For all other cases, the device type will be status

Example:

python tag_transformer.py sample_input.json 07

Output Format

The output will be a valid JSON array with the same structure as the input, but with the first value in each tagProps array replaced with the generated path.

Saving Output to a File

To save the output to a file, you can redirect the console output:

python tag_transformer.py sample_input.json 07 Conveyor > output.json

Requirements

• Python 3.6+
• No additional dependencies required
