I will clean, transform or automate your CSV, Excel or JSON workflow

I will clean, transform, validate or automate one clearly defined data workflow using Python.

Suitable for:

• CSV cleanup and restructuring
• Excel data processing
• JSON conversion and validation
• duplicate removal
• field mapping
• merging multiple files
• automated reports
• repeatable import/export workflows
• API data processing
• one-off data transformation scripts

What you receive:

• processed output files
• a reusable Python script where appropriate
• basic validation checks
• clear instructions for running the workflow again
• a short explanation of the transformation performed

Please provide:

• sample input files
• expected output format
• transformation rules
• any edge cases that should be handled

I use AI-assisted development together with manual review and testing.

This service covers one clearly defined workflow. Large datasets, complex integrations, dashboards and ongoing pipelines are quoted separately.
