Good day, Andrey!
In general, the task is clear, but for an accurate response regarding deadlines and price, I would like to clarify some questions that arose after analyzing your task.
Please write in private messages — we will discuss the details and your wishes.

Good day.
I will create a turnkey tool for converting an Excel document into the required XML format.
I have been developing and automating for marketplaces for many years, so I have a lot of experience and resources related to XML, XLS, and various formats.
I can create a program for Windows or a web application, depending on what is more convenient for you.
I am waiting for information from you about what is available as input and what format is needed as output.
I will do it urgently.

Good day, Andriy! If you do this regularly, you might try to automate it. It can also be done once, just translating one data format to another. I would like to see an example document and a description of the XML that should be in the result.

I have experience in converting documents from Excel to XML formats, so I can quickly and efficiently complete your task. It is important to receive a complete description of the XML for accuracy in the work process. Please share additional details so that I can provide a more accurate estimate. I look forward to your response.

Hello.
The task of converting xls to xml is completely clear and matches my qualifications. There are questions about how exactly you want to interact with the program (web, console, desktop application). In any case, I will be able to provide you with the maximum convenience of the chosen solution.
I look forward to hearing from you in private messages.

Hello.
Your task is not just to convert Excel to XML, but to build a reliable mechanism for generating invoices that consistently passes validation (including under KSeF) and does not break with real data.
I specialize in such tasks: document automation, XML/XSD, financial formats, integrations. I create solutions that work in production, not "one-time converters."
What I will implement:
— Full mapping of Excel → XML according to your specifications (considering nested structures)
— Generation of XML that complies with XSD (with a guarantee of passing validation)
— Validation layer (mandatory fields, formats, value checks before generation)
— Handling of edge cases (empty/incorrect data, different date/number formats)
— Error logging + clear messages (so you don't have to "search for the problem in XML")
— Batch generation (massively, without manual actions)
Solution format (of your choice):
— Excel + button (VBA / Power Query)
— a separate script (Python) with an interface
— or a hybrid for your process
Approach:
I immediately incorporate scalability — so you can generate hundreds of invoices without developer involvement.
The solution will be stable, documented, and suitable for further integration.
Work stages:
1. Analysis of your Excel + XML specifications
2. Prototype (1 invoice → XML, agreement)
3. Full implementation
4. Validation + testing on various cases
5. Handover + brief instructions
If necessary, I can sign a sole proprietorship/LLC.
If not just generation is important, but a guarantee of correct operation in the system — I will close the task turnkey.
I am ready to start immediately after access to examples.

Hello! I am ready to complete this project and have extensive experience in developing various applications.

I will consider an example of the input table, describe the output file, and propose an automated solution for generating such files based on the table.
Budget: 2000 UAH Deadline: 1 day
To implement, I propose two options:
VBA macro - a solution embedded directly in the Excel file, does not require third-party software, runs with a button directly from the table.
Python script - a more flexible solution, easily adapts to changes in the XML structure, convenient for automation and reuse.
To finalize, you need: Excel file (invoice) + description/schema of the XML structure.
