Excel & CSV Automation Services with Python

Common Problems I Solve

Problem 01

Manual Reports

Repeating the same spreadsheet steps every day, week, or month wastes time and increases the chance of human error.

Reports Excel

Problem 02

Messy CSV Data

Raw exports often contain inconsistent columns, empty rows, duplicated values, invalid dates, and formatting issues.

CSV Cleaning

Problem 03

Repeated Copy/Paste

Manual copy/paste between files is slow, fragile, and difficult to scale when the number of files increases.

Workflow Automation

What I Can Build

Deliverable 01

Report Generators

Python scripts that read raw data, calculate metrics, create grouped summaries, and export clean Excel reports with multiple sheets.

Pandas OpenPyXL Reports

Deliverable 02

CSV Cleanup Tools

Tools that standardize column names, remove bad rows, detect missing values, deduplicate records, and prepare data for reporting or import.

CSV Validation ETL

Deliverable 03

Multi-File Processing

Scripts that process many Excel or CSV files at once, combine data, apply rules, and generate one final output.

Batch Files Automation

Deliverable 04

Reusable Workflow Scripts

Clean Python scripts with documentation so the same reporting workflow can be reused without rebuilding everything manually.

How the Work Usually Goes

Step 01

Understand the current workflow

I review the current Excel/CSV files, the manual steps, the expected output, and the business rules that must be preserved.

Step 02

Build the automation script

I create a Python script that reads the source files, validates the data, applies cleaning rules, calculates summaries, and generates the final output.

Step 03

Test with sample files

I test the script with sample data and edge cases to make sure missing columns, invalid rows, and formatting problems are handled clearly.

Step 04

Deliver clean files and instructions

I provide the script, sample input/output, and a short README so the workflow can be run again when needed.
