Marketplace parser
Simple parser from the ROSSMANN marketplace.
We require a one-year service guarantee and assistance in fixing the parser if it stops working.
The specifications for the parser are written in the technical assignment.
The parser will process no more than 100 requests per run.
We need an .exe file for easy execution by someone who is not familiar with programming.

Hello.
I have reviewed your technical specifications for the Rossmann parser. I have done similar tasks — parsers for marketplaces and e-commerce sites in Python packaged as .exe for regular users to run.
Here is how I propose to implement the solution:
* A parser in Python with robust data extraction (working with dynamic pages if necessary)
* Limiting the number of requests per run (100) and appropriate delays to avoid blocks
* Error handling and logging so that the user can see if something goes wrong
… * Packaging the program into an **.exe file**, allowing it to be run with a double click without installing Python
* A simple user guide
It is also important to write the code modularly, so that if the website structure changes, selectors can be quickly replaced without rewriting the entire parser.
Regarding support:
I am ready to maintain the parser and fix it in case of changes on the Rossmann website.
A couple of clarifications regarding the specifications:
1. Is it necessary to save the history of already processed products to avoid duplicates?
2. In what format should the final file be (CSV / Excel)?
3. Is a simple interface needed, or is running through .exe sufficient?
After clarifications, I will be able to start working quickly.
Deadline: 2–3 days
Budget: 200–250 PLN

I propose to implement a parser for the Rossmann marketplace in Python. This will allow the creation of a simple tool for data collection according to the specifications, with a limit of 100 requests per run, packaged in an .exe file for convenient launching (without installing Python, with a possible simple interface).
What we will do:
- Parsing data from the Rossmann website (according to the specifications, with request processing)
- Automatic request limiting for stability
- .exe version for non-technical users (one-click launch)
- One-year warranty: assistance in updating/fixing if the parser stops working due to changes on the website
… I am ready to discuss the specifications, parsing details, and warranty conditions in the chat. We can start with a prototype.

I have experience in developing parsers for marketplaces and e-commerce sites (Allegro, Amazon, Shopify donors), as well as creating ready-made .exe utilities for Windows, so that people without technical knowledge can use the program. I have reviewed your technical specifications — the logic of parsing Rossmann → CSV for Allegro is clear, including the filtering conditions, HTML/JSON description formation, and Excel processing.
Technologies:
Python
Playwright / Selenium (stable parsing of JS sites)
Pandas / OpenPyXL (working with Excel/CSV)
… PyInstaller (.exe build)
I am ready to discuss the details, check the example CSV, and start development immediately.
Best regards,
Andriy

I am ready to create a parser according to your technical specifications.
Key points that I will implement:
Parsing MEGA and MARKI — navigating all pages, filtering only "Available online", entering the product card, collecting data.
Parsing ONE — single product without availability filter.
Working with the Allegro Excel template: filling in exactly by columns.
Saving CSV in UTF-8 with the correct encoding for Allegro.
Stack:
… Python 3.11 + Playwright + pandas/openpyxl + rich/logging + asyncio.
Launch modes: CLI (python parser.py --mode mega/marki/one --url ... --excel file.xlsx)
Error handling, retries, speed limit, headless mode.
I can start with a prototype for parsing one product card - I will show it in 1 day.

265 1 day55 USDHello.
I understood the task regarding Rossmann and your Allegro CSV template. We can create a parser for three modes: MEGA, MARKI, and ONE, with product availability checks, filling in the necessary columns, prices multiplied by 2 for PL, automatic prices for other markets, pulling in photos, EAN, item number, and generating descriptions according to your structure.
We will create a convenient launch through an exe file for Windows, so that a person without programming skills can run it. We will consider the limit of 100 requests per launch. We will add protection against duplicates, logging, and clear error messages.
Regarding support: we can provide support for a month for an additional fee. If the parser stops working due to changes on the website, we will promptly fix it.
To provide an exact price and timeline, we need to understand: what final format you need, one CSV per launch or accumulation in one file, and where to store the history of already processed products.

I am ready to implement such a parser in 5 hours. I have extensive experience in this field, as I have worked with the largest services in Poland, including: OLX, Otodom, Otomoto, MLS, and others. The technical specifications are clear and understandable, so to avoid wasting time, I suggest we discuss this quickly and get started on the work, so you already have the results in hand. I am willing to provide support for the bot, with minimal changes, as part of this deal indefinitely. Please write to me, I would be happy to collaborate with you.

426 10 0 7 days192 USDHello.
I am ready to implement a reliable and carefully written parser for the ROSSMANN marketplace with convenient launching via .exe and a guarantee of support.
I have experience in developing parsers for marketplaces and e-commerce platforms, including projects with bot protection, dynamic data loading, and changing page structures. I understand that the main value here is not just to "parse now," but to create a solution that will work reliably and can quickly adapt when necessary.
What you will receive:
A developed parser according to your specifications with processing of up to 100 requests per launch (this volume is absolutely comfortable and does not create a load).
… Correct handling of errors, timeouts, and retries.
Logging to understand the cause of failures.
A ready .exe file (built with PyInstaller) that can be run without installing Python and dependencies.
An instruction manual of 1-2 pages with a clear description of how to launch.
Regarding the 1-year guarantee:
I am ready to provide warranty support for a period of 12 months. If the website changes its structure and the parser stops working, I will make adjustments at no additional cost (provided that the logic of the specifications does not change drastically). I will also be available for consultations on launching.
Regarding implementation:
I will do it either through requests (if the data is available without complex protection) or through Selenium/Playwright — depending on the structure of the website and the requirements of the specifications. I will prefer the most stable and easy option.
The completion time is 4-7 days after the specifications are approved.
The cost for the project is 700-1000 PLN, including the .exe build and one year of support.
I am ready to review the specifications and immediately provide a final accurate estimate of the timeline and budget.

1588 9 0 3 days110 USDHello! I am ready to develop a parser for ROSSMANN according to your specifications.
Here’s how I will implement it:
Format .exe and convenience: I will compile the script into a single file that can be launched with a double click. For maximum convenience for a non-technical user, I will create an understandable visual interface (based on PyQt/PySide) — it will be a neat program with a field for entering links and a "Start" button, rather than just a black console.
I will write modular and clean code (Python). If ROSSMANN updates and changes the layout — I will promptly adjust the selectors. I confirm support for one year.
Speed and security: 100 requests is a small load. I will configure the correct headers and pauses so that the marketplace does not block the program.

I will do all three parsing modes, I will take into account the conditions for product availability, and I will fill out the Excel according to your rules. I will package it in .exe, it runs with a double click, no installation is needed.
I am ready to provide a one-year warranty, we will keep the parser in working condition and fix it if something changes on the website.
To start, I need one file from you: the Excel template from Allegro (the one generated in SalesCenter). Without it, I cannot specify an exact deadline, but approximately 5-7 days for the full version.
