Excel Master File Division Using Python

@WycOj

As a biostatistician and experienced data analyst, I've been designing and conducting analyses on large datasets for over seven years now. My skillset ranges from data cleaning and coding to deep learning and predictive analytics using tools such as Excel, Python, R, SPSS, and more. Your requirement of extracting specific data from a master Excel file with reliability and preserving all formatting is something that I have done countless times in previous projects. Furthermore, my expertise in various Python libraries that you mentioned like pandas for data manipulation and xlwt/xlrd for handling .xls files equips me perfectly for this task. I guarantee clean, well-commented and maintainable code which won’t need any further assistance after the project is completed. And let's not forget about the README file – clear instructions are as important to me as they are to you. All in all, I understand that an efficient project completion hinges on a graceful fusion of technical know-how and practical attention to detail. With my in-depth experience with medical data analysis and data science, I am confident that I can split your excel master file accurately into separate files by client without losing any information or formatting. Let's get started on this task together!

Hello, HAVE HANDS-ON EXPERIENCE WITH SUCH PROJECT I bring 11+ years of proven experience in data handling, automation, and spreadsheet-based workflows, and I clearly understand the need for accurate, well-organized, and clean datasets. The goal is to deliver a structured, error-free master file with clearly organized data that’s easy to review, maintain, and scale for future use. Core features: -->> accurate data entry & validation -->> Excel/Google Sheets organization -->> data cleaning & formatting -->> consistency checks -->> timely delivery My approach focuses on precision-first workflows, clear structure, optional Python-based automation where helpful, and a clean, well-documented process to ensure reliability. I’d be happy to continue in chat, as I have a few questions about the data volume, structure rules, and any specific formatting preferences before proceeding. Thanks Julian

Attached are Python-based Excel automation projects I’ve delivered where formatting, calculations, and client-level file outputs were preserved exactly. You need a reliable script that splits a master .xls by client, performs calculations, and outputs clean, formatted Excel 97–2003 files without breaking styles. → Read the master .xls, extract cost columns, and apply required calculations deterministically → Split data per client and export individual .xls files while preserving conditional formatting and cell formats → Deliver a Windows-ready CLI script with commented code, README, and a verified sample output Using openpyxl-compatible logic for calculations while handling legacy .xls export carefully avoids format loss and brittle conversions. I have 10+ years of hands-on experience building Python automation around Excel workflows, including legacy .xls handling, formatting preservation, and batch file generation. On similar jobs, my scripts were reused monthly by non-technical teams with zero maintenance issues. My experience includes pandas, xlrd/xlwt, Excel formatting control, CLI tools, and production-safe scripting. Do you have a sample master file I can inspect for conditional formatting rules, and is the client identifier always consistent in one column?

@sf264

Hello, I am eager to develop a small, reusable script that will process a master Excel file containing all client data. The script will have all the given functionalities. I have achieved 100 percent success in working on similar projects and would love to replicate that success in your project as well. Let's collaborate and I promise to give my best to your project. I have some questions to help get a clearer scope of the project, so I'm looking forward to discussing further and sharing my results-oriented ideas, Fahad.

Having extensive experience in Data Management, Data Processing, Excel and Python, I believe I am well-suited for your project. My work across various industries including fintech and healthcare has given me an in-depth understanding of the importance of accurate data management and automation. Using my skills, I’ll create a clean, well-commented, and reusable script to process your master Excel file effortlessly. My proficiency in libraries like pandas and xlwt/xlrd combined with my ability to leverage Python scripting for Excel automation make me specially fit for your project. I will ensure that the script meticulously extracts the total cost column, performs necessary calculations, splits the data by client accurately while preserving any conditional formatting or number/date formats. The subsets will then be saved as separate Microsoft Excel 97-2003 (.xls) files which will be compatible across platforms. Moreover, as a full-stack developer familiar with command-line execution on Windows systems, I guarantee a user-friendly interface which will simplify executing the script. I understand the value of maintainable code in long-term projects, so you can expect a detailed README alongside one sample output file for your verification. My presence on this platform for years is testament to my dedication and reliability. With this I can assure you high-quality deliverables within your timeline at efficient pricing. Choose me for a seamless turnaround!

@micecats

Hi there, I can build this automation tool for you. I noticed a specific technical challenge in your request: preserving Conditional Formatting in the older .xls (97-2003) format. Standard Python libraries (like pandas/xlwt) drop conditional formatting when writing to .xls. TO SOLVE THIS, I WILL USE A DIFFERENT APPROACH: Method: Instead of rebuilding the file from scratch, I will use xlwings (or win32com) to automate the Excel application directly on Windows. Logic: The script will open the Master File, compute the costs, and for each client, it will "Save As" a new copy and delete the irrelevant rows. Benefit: This guarantees that 100% of your formatting, conditional rules, and cell styles are preserved perfectly in the output .xls files. I will compile this into a standalone .exe so you can run it with a double-click. I have strong experience with legacy Excel automation and can deliver this within your timeline. Best regards,

@NazarKanteruk

Hey I hope you are doing well. I'd like to do this project. I'm proficient in the relevant skills (Python, Excel file parsing, automation), and believe I would be a good candidate for this project. If you think it'd take 3-5 days it must be a doozy. Nevertheless, I believe I can deliver good results and would love to be of assistance to you. Please message to discuss further. I hope to hear from you. Thanks.

@Abutalha5

I’m a Python developer with strong experience in Excel automation, including working with legacy Excel 97–2003 (.xls) files while preserving formatting and usability. I’ve built repeatable scripts that split large master workbooks, apply calculations, and generate client‑specific outputs without breaking conditional formatting or number/date styles. For this task, I’ll deliver a clean, command‑line Python script that reads the master file, processes the Total Cost column, splits data by client, and exports individual .xls files with the original look and feel intact. The delivery will include well‑commented code, a short README, and a sample output file for verification. I can complete this reliably within 3–5 days and ensure the script is easy to reuse going forward.

@vudinhgiang

Hi, I’m **Giang** — thanks for the clear project description. This is **not an automatic bid**: I can develop a **Python script** that reads your master `.xls` file, extracts the total cost column for calculations, splits the rows by client, and saves each client’s subset as a **separate Excel 97-2003 `.xls` file** while preserving all conditional formatting and cell-level number/date formats. I’ll use libraries like **pandas** combined with **xlrd/xlwt** or **openpyxl** as appropriate to maintain formatting. Deliverables will include a **clean, well-commented, and maintainable script**, a short README with usage instructions, and one sample output file for verification. The script will be **command-line executable on Windows**, ready for reuse. Estimated timeline aligns with your expectation: **3–5 days**. I respect your project, believe it’s a strong fit for my Python and Excel automation experience, and I’m excited to deliver a reliable solution. **Best Regards,** Giang
