MLOps Workflow Normalizes and Enriches Occupational Wage Data from Excel
Why does a personal machine‑learning experiment need a full‑blown MLOps pipeline? The author of “Building Practical MLOps for a Personal ML Project” argues that even a modest analysis of state‑level wage figures can quickly become tangled without disciplined data handling. The source material lives in a sprawling Excel workbook, mixing text labels with raw numbers, and spans dozens of occupational categories across the United States.
Without a repeatable process, each downstream statistical test—whether a plot, a T‑test, or a regression—would have to redo the same messy transformations. The workflow described in the article therefore treats the raw spreadsheet as a single point of truth, applying systematic cleaning, type conversion, and standardization of geographic and occupational identifiers before any analytical step. By attaching auxiliary columns such as total payroll, the pipeline creates a stable foundation that can be called upon by every subsequent model or hypothesis test.
This disciplined approach promises consistency, reduces error, and makes the entire analysis reproducible.
occupational wage data is: - Loaded from the Excel file - Cleaned and converted to numeric - Normalized (states, occupation groups, occupation codes) - Enriched with helper columns like total payroll From then on, every analysis -- plots, T-tests, regressions, correlations, Z-tests -- will reuse the same cleaned DataFrame. // From Top-of-Notebook Cells to a Reusable Function Right now, the notebook roughly does this: - Loads the file: state_M2024_dl.xlsx - Parses the first sheet into a DataFrame - Converts columns like A_MEAN ,TOT_EMP to numeric - Uses those columns in: - State-level wage comparisons - Linear regression ( TOT_EMP →A_MEAN ) - Pearson correlation (Q6) - Z-test for tech vs non-tech (Q7) - Levene test for wage variance We'll turn that into a single function called preprocess_wage_data that you can call from anywhere in the project: from src.preprocessing import preprocess_wage_data df = preprocess_wage_data("data/raw/state_M2024_dl.xlsx") Now your notebook, scripts, or future API call all agree on what "clean data" means.
What does the guide achieve? It walks a personal‑project notebook through the stages required for a reproducible, deployable MLOps pipeline, ending with a portfolio‑ready artifact. By loading occupational wage data from an Excel file, cleaning it, converting fields to numeric types, and normalising state, occupation‑group and occupation‑code columns, the workflow creates a tidy base.
Helper columns—such as total payroll—are then added, giving analysts ready‑made features for downstream tasks. Consequently, plots, t‑tests, regressions, correlations and z‑tests can all draw from the same enriched dataset without repeating preprocessing steps. The article shows each transformation step in detail, which should aid anyone looking to replicate the process on similar data.
Yet, it remains unclear whether the same sequence will handle larger, messier sources or integrate smoothly with automated CI/CD pipelines beyond a personal setting. The author’s emphasis on reproducibility is clear, and the step‑by‑step layout provides a concrete template; whether it scales to production‑level workloads is still an open question.

Common Questions Answered
What is CSVAI and how does it automate data enrichment?
[zyxware.com](https://www.zyxware.com/article/6935/csvai-automate-data-enrichment-any-csv-or-excel-file-generative-ai) describes CSVAI as a Python library and command-line tool that applies AI prompts to every row in CSV or Excel files. It can analyze textual data and image URLs, using multimodal OpenAI Vision APIs to enrich data and generate structured outputs.
What are some key use cases for CSVAI?
CSVAI can be used for multiple data enrichment scenarios, including enriching lead databases, summarizing customer reviews, categorizing support tickets, and extracting structured values from unstructured text. It can also automatically generate product descriptions, analyze user-uploaded images, and perform initial damage assessments by analyzing photos in claim files.
What are the key features of CSVAI?
CSVAI offers structured outputs with JSON Schema to enforce consistent and validated results. The tool is designed to be crash-safe and scalable, allowing users to enrich large datasets using AI without needing to build custom applications for every use case. It supports both text and image analysis across various domains.
