I will automate your excel and CSV workflow with python
Jan Frau
About this gig
Do you repeat the same file-processing task every week? I will build a small Python script for one clearly defined workflow.
Examples include combining CSV exports, cleaning recurring data, validating rows and generating a summary report. Excel input or output is available when agreed in the scope.
You receive readable Python source code, setup and run instructions, a sample input and output, and checks for the agreed rules. Invalid or conflicting records can be separated into a review file instead of silently changing your data.
Basic covers one local CSV workflow with one input layout, up to 3 matching files and 3 processing steps. Standard adds Excel support or a formatted report. Premium adds a second compatible layout and a summary report.
Message me with a sample, your operating system and the exact result you need before ordering. APIs, scraping, cloud deployment, desktop apps and ongoing maintenance require a separate quote. Revisions cover the agreed workflow.
I use AI-assisted development and test the script. Portfolio examples use fictional data.

I help with Excel and CSV cleanup and small Python automations. My services focus on organizing spreadsheets, removing duplicates, combining exports and creating repeatable reports. I use AI-assisted tools and check the results against the agreed requirements. You receive clear files, practical instructions and a summary of the work. Send a small sample and your desired output so I can confirm the scope before you order.
FAQ
What is one workflow or processing step?
A workflow turns agreed input files into one defined set of outputs. A step is one operation such as merging files, applying an agreed validation rule or calculating a category summary. We confirm the steps before ordering.
Can I run the script on Windows or macOS?
Tell me your operating system and Python version. I provide instructions for the agreed environment. Installing Python may be required; a standalone executable is not included.
Will it handle any CSV or Excel file?
It supports the agreed input layouts, delimiters, date formats and file sizes. Basic is for local CSV files; Excel support is available in the larger packages. Send samples before ordering.
Does the price include APIs or hosting?
No. API integration, cloud hosting, paid tools, scraping and scheduled deployment require separate scoping. Local scripts and run instructions are included.
What happens when the input has errors?
The script checks the agreed rules and reports errors or separates affected records for review. It does not silently invent missing data.
What does a revision cover?
Corrections to the original agreed workflow. New features, new input layouts and ongoing maintenance are additional scope.
Do you use AI during development?
Yes. I use AI-assisted development, review the code and test the agreed behavior. Mention confidentiality requirements or AI restrictions before ordering.
