I need a small Windows desktop utility that automates downloading prescribing data from the OpenPrescribing API. The workflow is straightforward: I will place a plain-text file in a folder; each line of that file contains one BNF code. When I click “Start” in the app, it should loop through every code, call [login to view URL]{CODE} download the CSV returned by the API, and save it into an output folder I choose, using the exact code as the filename (e.g., [login to view URL]). Essential needs • Windows-only build. • Simple graphical interface: a field to browse for the text file, another to choose the destination folder, a “Start” button and a progress indicator (percentage or per-code status is fine). • Robust error handling—if a code is invalid or the request times out, log the issue and move on so the run finishes. • No browser automation; use a direct HTTP request so the process is fast. • Clean codebase that I can recompile later if needed (Python with tkinter, C#, or any language that produces a single-click Windows EXE is acceptable). Deliverables 1. Compiled Windows executable. 2. Read-me or brief video showing how to run it. 3. Full source code with comments so I can maintain or extend it. I’ll test by feeding four sample codes; if each produces a correctly named CSV in the chosen folder, the job is complete.

Built quite a few similar utilities - stuff that reads a list of inputs, calls an API in a loop, and saves the output in a clean structure. This one is pretty simple to scope out. I'd write it in Python (tkinter for the GUI) so you get a single .exe, no install needed. Logic: load your BNF codes from the text file, loop through each, call the OpenPrescribing spending_by_org endpoint with a direct HTTP request (no browser involved), save each CSV as {code}.csv in your chosen folder. Progress indicator will show per-code status, errors get logged so the whole run completes even if a code is invalid. Full source code included with comments so its easy to extend later. Can start today. - Usama

Hello, I’m excited about the opportunity to contribute to your project. With my expertise in Windows desktop development using Python (tkinter) or C#/.NET, HTTP API integration, CSV/file I/O automation, and robust error handling and logging, and a strong focus on clean, scalable implementation, I can deliver a fast Windows utility that reads BNF codes from a text file, calls the OpenPrescribing endpoint per code, and saves each returned CSV to your chosen folder using the exact code as the filename. I’ll tailor the work to your exact requirements, ensuring a simple GUI with file/folder pickers, a Start button, progress and per-code status, timeout/retry handling, and a clear run log that records invalid codes or request failures while continuing so the full batch completes reliably without browser automation. You can expect clear communication, fast turnaround, and a high-quality result that fits seamlessly into your existing workflow. Best regards, Juan

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have developed similar Windows desktop tools that automate data downloads from APIs using clean codebases and straightforward GUI designs that work seamlessly. The key to completing this project successfully is implementing robust, direct HTTP requests with error handling to ensure uninterrupted downloads and easy maintenance. Approach: ⭕ Build a simple GUI with input fields to select the text file and output folder using Python tkinter or C#. ⭕ Loop through each BNF code from the text file, perform direct HTTP API calls, and save each CSV using the code as filename. ⭕ Implement progress indicators and detailed error logging that continues on failure. ⭕ Deliver a compiled Windows EXE along with full commented source code and easy-to-follow documentation or video. ❓ Could you please confirm the preferred programming language for the executable (Python or C#)? ❓ Should the error log be a separate file or displayed within the app interface? I am confident I can deliver a reliable, user-friendly utility with maintainable code quickly. Looking forward to your reply. Thanks, Nam

Hi, As per my understanding: You need a lightweight Windows-only desktop utility that reads BNF codes from a text file, calls the OpenPrescribing API per code, downloads the returned CSV, and saves each file using the exact code as the filename. The app must include a simple GUI (file picker, output folder selector, Start button, progress indicator), handle errors gracefully, avoid browser automation, and be delivered with source code and a compiled EXE. Implementation approach: I will build this in Python using requests for direct HTTP calls and tkinter for a minimal GUI. Workflow: • Parse text file line-by-line (trim/validate codes). • For each code, send GET request to the API endpoint. • On 200 response, stream-save CSV as {CODE}.csv in selected folder. • Log failures (timeout, 404, malformed response) into a run log file and continue. • Update progress bar and per-code status in real time. The project will be packaged into a single Windows executable using PyInstaller, with clean, modular code for easy recompilation. A few quick questions: • Expected max number of codes per run? • Do you require retry logic for failed requests? • Proxy or firewall constraints? • Preferred log format (TXT or CSV)?

Hey! I can whip up a small Windows app that takes your text file of BNF codes, hits the OpenPrescribing API for each one, and drops the CSVs in your chosen folder. It’ll have a simple GUI with browse buttons, a start button, and a progress indicator, plus error handling so it keeps going if a code fails. I’ll give you a compiled EXE, the full commented source, and a quick guide/video on how to run it.

Hope you are doing well! I have built Windows desktop utilities that automate API downloads and file processing, including Python/tkinter and C# EXE solutions. In similar projects, I created simple GUIs with file/folder selectors, progress indicators, and robust error handling so the workflow continues even if some requests fail. I’ve worked with CSV APIs, looping through codes, saving results with code-specific filenames, and logging errors for later review. Challenges I’ve resolved include handling API timeouts, invalid codes, and ensuring the GUI remains responsive during long loops by using background threads. I provide clean, commented code so future maintenance or recompilation is straightforward, and include clear instructions or short videos for running the tool. I can deliver a fully functional Windows EXE, source code, and documentation that meets your test scenario with four sample BNF codes. I am ready for you and waiting here. Thank you.
