When it comes to working with data, ChatGPT can prove to be an invaluable assistant, helping users consolidate, clean, analyze, and Visualize data seamlessly.

3. Consolidating Excel Files

3.1. Gathering the Files

One common task when working with Excel data is consolidating multiple files into a single dataset. This is often done to combine data from different sources or to merge data from different periods. In our example, we'll be consolidating several Excel files containing financial data for each date. These files represent sales reports from different branches, for instance.

To begin the process, we'll need to Gather the files that need to be merged. You can specify the location of the files using Python, along with the necessary libraries like pandas. ChatGPT can help generate the code to retrieve the files from a specific folder and prepare them for consolidation.

3.2. Merging the Files

Once we have gathered the files, the next step is merging them into a single dataset. This involves reading each individual file, creating a pandas DataFrame for each file, and then appending these DataFrames to a combined DataFrame. By doing this, we'll have a consolidated dataset containing the data from all the Excel files.

To accomplish this, we can leverage the power of the pandas library in Python. By providing the necessary code prompts to ChatGPT, we can generate the code required to merge the Excel files, resulting in a unified dataset.

4. Cleaning and Preparing the Data

After consolidating the Excel files, the next step is to clean and prepare the data for further analysis. Data cleaning involves removing duplicates, handling missing values, standardizing data formats, and resolving any inconsistencies. By ensuring the data is clean and organized, we can avoid potential errors and obtain accurate insights.

4.1. Removing Duplicates

Duplicate records can be a common occurrence in datasets, especially when merging data from multiple sources. Removing duplicates is an essential step to ensure the accuracy of our analyses. With the help of ChatGPT, we can generate the code to identify and remove duplicate records from our consolidated dataset.

4.2. Handling Missing Values

Missing values can pose a significant challenge when working with data. They can affect the accuracy of our analyses and lead to biased results. It is crucial to handle missing values appropriately, whether by imputation (substituting missing values with estimates) or by removing records with missing values. ChatGPT can assist us in generating code snippets to handle missing values effectively.

5. Performing Basic Analysis

Once the data is clean and prepared, we can proceed with performing basic analysis to gain insights and answer specific questions. In our example, we'll demonstrate how to calculate the total revenue, expenses, and profit for each category using the cleaned data. However, keep in mind that you're not limited to these calculations and can perform more complex analyses based on your specific requirements.

To generate code snippets for performing basic analysis, we can provide prompts to ChatGPT explicitly stating the calculations we want to perform. By utilizing the power of pandas and other data analysis libraries, we can obtain the desired results efficiently.

6. Creating an Excel Report with a Chart

Once we have performed the necessary analysis, it is often helpful to present our findings in a visually appealing format. Excel reports with charts are a popular choice for data visualization due to their versatility and familiarity. With ChatGPT, we can generate code snippets to create an Excel report with a chart that highlights our analyzed data.

By specifying the desired chart Type, data ranges, labels, and formatting preferences, ChatGPT can assist in generating the necessary code to build the report. This allows us to effortlessly transform our analyzed data into a visually impactful presentation.

7. Generating an Interactive Plot

While Excel reports with static charts can be informative, interactive plots can provide a more engaging and customizable experience for data exploration. By utilizing libraries like Plotly, we can generate interactive plots that allow users to toggle between different KPIs and explore the data in an intuitive manner.

By providing the necessary prompts, we can leverage ChatGPT to generate code snippets for creating interactive plots using Plotly. The generated code can be easily integrated into your Python workflow, enabling dynamic and interactive data visualization.

8. Building a Dashboard using Streamlit

In addition to interactive plots, we can take our data visualization a step further by building entire dashboards. Dashboards provide a comprehensive view of multiple data visualizations and allow users to navigate through different views and perspectives seamlessly. With the Python library Streamlit, we can create interactive and responsive dashboards that can be deployed locally or on the web.

By leveraging ChatGPT, we can generate code snippets to build a Streamlit dashboard that incorporates our analyzed data and interactive plots. The generated code can be customized further based on specific dashboard requirements, such as headers, subheaders, and additional visual elements.

9. Improving the Code

Once we have a working script, it is essential to improve the code's quality, readability, and maintainability. While the code generated by ChatGPT might work, it may not adhere to best practices or be structured optimally. By instructing ChatGPT to enhance the code, we can obtain more Pythonic, modular, and robust code snippets.

To improve the code, we can prompt ChatGPT to refactor the code by separating the different steps into functions, using appropriate libraries (such as pathlib instead of os), and ensuring the code follows best practices. This step ensures that the generated code is more manageable, reusable, and maintainable in real-world scenarios.

10. Using Power Query for Consolidation

Although we have primarily focused on using Python and libraries like pandas for consolidating Excel files, it is worth mentioning that there are alternative approaches available. Microsoft Excel itself provides a powerful tool called Power Query, which offers a user-friendly interface for consolidating and transforming data.

By integrating Power Query into our workflow, we can leverage the capabilities of Excel for data consolidation and transformation.
