I have several CSV files full of text-based records that need to be cleaned before they move further down our pipeline. Specifically, the script must: • Reformat every date it encounters into a single, consistent style I will provide (the files mix multiple regional formats at the moment). • Identify and remove any duplicate rows so each record is unique. The input is strictly text data stored in standard CSV format—no Excel or JSON involved for now. A single, well-structured Python file that I can drop into an existing workflow is the ideal deliverable, along with a brief README that shows the command-line call, required libraries, and an example before-and-after snippet. If you prefer pandas that’s fine; just keep the code clear and documented so I can tweak or extend it later (for example, I may want to add standardizing text casing in a follow-up task). Once the script can process a sample file end-to-end without errors and the output passes a quick diff check, the job is done.

Hi there! I understand your CSV files are currently inconsistent in formatting, especially with mixed date formats and duplicate records, which can break your downstream data pipeline and create errors in analysis. I have solid experience in Python scripting, data processing, and working with pandas for cleaning large datasets. I have handled similar tasks where messy CSV data was standardized, deduplicated, and prepared for automated pipelines in a clean and reusable way. My approach will focus on building a simple, well-structured Python script using pandas to normalize all date formats into your required standard and remove duplicate rows accurately. I will ensure the script is clean, modular, and easy for you to extend later (like adding text normalization or extra validation rules). I will also include a clear README with usage instructions and a before/after example so you can quickly verify results. check our work https://www.freelancer.com/u/ayesha86664 Which date format would you like the final output standardized to (e.g., YYYY-MM-DD or DD/MM/YYYY)? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Hello Sir, Having spent nearly a decade skillfully developing full-stack applications using Python, JavaScript, and PHP, I wholeheartedly believe I'm the perfect fit for your CSV data formatting project. My extensive experience includes designing robust API's, creating reliable software systems that scale, and ensuring seamless deployment across varied cloud infrastructures. This experience has provided me with an in-depth expertise in handling and cleaning data like the task you need to be done. Furthermore, my proficiency in using Pandas, Python's highly efficient data manipulation library, well complements your project requirements. Though I have used Pandas to build several ETL and data processing solutions in the past, I am more than happy to adopt your preferred approach. As a veteran tech professional, adaptability is a key quality I cultivate. Lastly, hiring me means securing not only an expert coder but also someone who will meticulously document the entire process to facilitate any future tweaking or extending of the script. From the initial design to the final diff check - I see this as a journey towards building better pipelines together. Being offered this project wouldn't just be about completing it but making sure your workflow is mobile and efficient even beyond this task. If you're ready for an error-free dataset that is unified in style and absolutely unique, let's get started! Thanks! John

I can deliver a clean, well-documented Python script (pandas-based) that standardizes all date formats to your specified style and removes duplicate rows reliably. The solution will be modular and easy to extend (e.g., for text normalization later). I’ll include a concise README with setup, dependencies, command-line usage, and before/after examples. The script will be tested on a sample CSV to ensure accurate transformation and smooth integration into your pipeline.
