How to fix Long Method Complexity Many Parameters

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.
For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.
Commonly applied refactorings include:
If many parameters/temporary variables are present:
- Replace temporary variables with Query
- Introduce parameter object; often combined with preserve whole object
- If the above two are insufficient: Replace method with method object
If you have long conditionals: Decompose Conditional
Otherwise: Extract method
Complexity

Complex classes like excelexporters.virtualmetercarbon.generate_excel() often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
Many Parameters

Methods with many parameters are not only hard to understand, but their parameters also often become inconsistent when you need more, or different data.
There are several approaches to avoid long parameter lists:
If you can get the data from another object that the method knows about already: Replace the parameter with method call
If several parameters are part of another object: Preserve Whole Object
If parameters are not yet connected: Introduce Parameter Object

Virtual Meter Carbon Excel Exporter

This module provides functionality to export virtual meter carbon emissions data to Excel format.
It generates comprehensive reports showing carbon dioxide emissions for virtual meters
with detailed analysis including base period comparison and time-series data.

Key Features:
- Virtual meter carbon emissions analysis
- Base period vs reporting period comparison
- Detailed data with line charts
- Multi-language support
- Base64 encoding for file transmission

The exported Excel file includes:
- Virtual meter carbon emissions summary
- Base period comparison data
- Detailed time-series data with line charts
- Parameter data (if available)
