The following code defines a CSVMapper class which is a subclass of QMainWindow . The purpose of this class is to map data from one CSV format to another using a template.
The class has several methods that handle different operations such as loading templates, loading data, adding mappings, converting data, and more.
The program starts by importing necessary libraries and modules, and defining the QMainWindow subclass CSVMapper . It then defines various methods for the CSVMapper class and initializes the PyQt5 application. The class is instantiated, and the PyQt5 application is executed.
Some of the key methods in the CSVMapper class are:
- init : initializes the CSVMapper class, setting up the UI and connections
- customise_gui : customizes the UI elements, such as adding items to the combobox
- load_template : loads the selected template into the template_table
- transform_data : transforms the data from the input CSV file based on the selected template
- on_convert_data_pressed : converts the data and saves the output as a CSV file
- on_save_data_pressed : saves the modified data in the tableWidget_result to an output CSV file
The user can choose a template from the dropdown menu, load the data from a CSV file, map the fields as required, and then convert the data according to the chosen template. The program also provides functionalities like adding sequential index values, updating cell values manually, and searching and replacing cell values in the output table. Finally, the user can save the modified output data to a CSV file.
