Need clean, organized Excel or CSV data? I can clean and merge your files, standardize formatting, and automate repetitive spreadsheet tasks with Python.


Services include:

- Removing duplicate records

- Standardizing dates, column names, and formats

- Handling missing values based on your instructions

- Merging files with compatible structures

- Creating a reusable Python script for one agreed workflow


Packages:

Basic: Clean and format 1 file, up to 1,000 rows.

Standard: Merge and clean up to 5 files, up to 10,000 total rows.

Premium: Process up to 10 files, up to 20,000 total rows, with a reusable Python script and README.


You will receive the processed Excel or CSV files. Source code is included in Premium only. I check the output against your agreed requirements before delivery.


Each package includes 1 revision within the original scope. New tasks require a separate quote. API integration, database connections, and app interfaces are not included.


Please message me before ordering with an anonymized sample, your processing rules, and the desired output so I can confirm the right package.
