Good day, Vitaliy!
Overall, 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.

Hello!
I am ready to take your project to work. I have experience building complex relationships in Excel and understand how to set up the architecture so that all 21 sheets work as a single logical model.
What I offer:
1. Reliability: I will use formulas that work consistently in older versions of Excel (without crashes when opening).
2. Logic: I will set up the sequence so that changes in data in one place are correctly reflected throughout the file.
3. Deadlines: I will meet your 2-day timeframe. I work quickly and for results.
I would be happy to review your file and discuss the details of the relationships. I am ready to start right now!
We can discuss payment in private, as I can take it not expensively because I am currently working more for the sake of reviews.

Good day.

I am ready to complete the task after auditing the file, namely:
check the architecture of the model between 21 sheets
build correct inter-sheet connections
write stable formulas without circular dependencies
optimize calculations
ensure compatibility with older versions of Excel (without using functions that are not supported there)

… After a quick technical audit of the file, I will be able to confirm completion in 1 day if:
the structure of the sheets is already logically divided
the main calculation blocks are defined
functions from new versions of Excel (XLOOKUP, FILTER, UNIQUE, etc.) are not used
there are no circular references or critical architectural errors

Please send the file for a brief audit privately.

Good evening, if you are online, we can start now. Are there specific tasks and formulas?

Hello! Could you show a file or an example of the structure (21 pages) so that I can assess the complexity of the relationships between the tables? After that, I will be able to confirm the deadline and budget accurately.

Good day.

I have experience in building logical models in Excel and linking multi-sheet files with formulas without using modern functions (for compatibility with older versions of Excel).

I am ready to:
• analyze the file architecture
• establish correct links between 21 sheets
• ensure logical consistency of calculations
• optimize formulas for stable operation
…
I am ready to complete this within 2 days after reviewing the file.

I would be happy to review the file before final approval.

Hello!
I have been working with formulas since 2008, with VBA-Excel (macros) since 2011.
My priorities are optimizing calculations and user convenience.

Let's take a look at the file.

Good day
I am ready to take on the project. I will conduct a structural audit of all sheets, build the correct logic of dependencies, and systematically link the model with formulas without violating the architecture of the file.
I will process the file considering compatibility with older versions of Excel (without using new functions that may not be supported).

Good day. I can do it. However, I will need details on what exactly we are calculating. Please contact me in private messages.

Good day.

To assess the scope of work, it is necessary to review the Excel file itself and understand the logic between the 21 sheets.

After the review, I will be able to:
- build correct links between the sheets
- rewrite formulas for compatibility with older versions of Excel
- optimize calculations so that the file works quickly

… Please send the file for preliminary analysis.

Hello!

I am ready to connect all 21 sheets in your Excel file into a single logical system in 2 days, so that everything calculates correctly and opens in older versions of Excel.

I have experience working with complex multi-sheet tables: I build dependencies correctly, eliminate circular errors, optimize formulas, and make the structure understandable for further work.

What I will do:
- Set up logical connections between all sheets
- Write correct formulas without conflicts
… - Ensure compatibility with older versions of Excel (without new functions)
- Check the speed and stability of the file's operation

I can start immediately after receiving the file.
I guarantee careful implementation and a working result within the specified timeframe.

I look forward to collaborating!

Good day. I suggest we discuss the project in more detail, as it is difficult to talk about deadlines and costs without seeing the actual file.

Good day,
An interesting and understandable task.
It is necessary to take a detailed look at the file and all the sheets to propose the best solution. After all, there are volatile functions, such as offset or index, through which the file may freeze.

I will review the file and suggest an implementation. Which version is considered "old"?

Hello!
I have reviewed the task in your file. Building the logic on 21 sheets so that everything "flies" and does not produce errors in older versions of Excel is an interesting task and I understand it. The main problem usually is that new functions (like XLOOKUP or FILTER) simply do not work in older versions, turning the file into a set of #NAME? errors.
What I propose to do in these 2 days:
Full compatibility (Legacy Support): I will rewrite all connections using the "gold standard" — combinations of INDEX + MATCH and SUMPRODUCT. This guarantees stable operation in Excel versions 2010, 2013, and above.
Logical architecture: I will link all 21 sheets into a single system. You change data in one place — the result automatically updates throughout the chain.
Speed optimization: I will remove "heavy" formulas that make the file "think" for 10 seconds after each entered number.
Integrity check: I will test all loops (to avoid circular references) and output the main indicators to the final dashboard or summary sheet.

Good day!

I am ready to build the correct logic from your prepared Excel file (21 sheets) and link everything with formulas so that the structure works as a single system with the correct sequence of calculations.

I will provide:
• correct inter-sheet links;
• stable operation of formulas without errors;
• compatibility with older versions of Excel (without using new functions that are not supported);
• verification of the logic of calculations;
… • optimization so that the file opens quickly and without crashes.

I look forward to collaborating! :)
