Good day.
I can help with this task. To be honest, I wouldn't consolidate everything into one "big Excel" file, because with 20+ files of 200+ thousand rows each, it starts to feel more like a punishment than a tool for analysis.
I would suggest a slightly more proper solution:
- consolidation of all Excel files into a single structure
- loading data into a database
- building pivot tables / selections based on the required parameters
- the ability to add new files without involving a developer
- preparing a foundation for further analysis, filtering, BI, or modeling
What I can propose for implementation:
- PostgreSQL as the main database
- import from Excel through a separate understandable script or simple interface
- normalization and cleaning of data during loading
- formation of pivot tables / views for analysis
- instructions so you can update the data yourself later
In the end, you will receive not just "one file," but a working tool that does not break under the volume of data and allows you to work calmly with analytics.
If needed, I can also help separately:
- think through the database structure
- create automatic updates
- connect Power BI / Excel / Python analytics on top of this database
For an accurate estimate of timelines and costs, it would be good to look at 1-2 sample files and understand:
- whether they have the same structure
- which fields are important for analysis
- which pivot tables / selections are needed as output

Good day
20+ files have the same column structure?
I can offer you to do everything based on a database + Django admin panel.
I completed a similar project a couple of days ago. It required processing and calculating data on 2,500,000 records. I will quickly adapt it to your files.

There is experience in creating scalable solutions for working with large volumes of data (over 4 million rows), using MySQL/PostgreSQL and effective aggregation. A process can be prepared to consolidate these Excel files into a single database with a convenient structure for quick construction of pivot tables or custom filtering.
I propose to create a database on PostgreSQL with carefully thought-out indexes and schema, as well as to develop an interface (possibly on Laravel/Vue) that will allow easy updating/adding of new files through a web form without involving a developer. If necessary, the import can be automated through scripts or even set up an ETL process.
I am ready to discuss the details of parameters and data formats to choose the most optimal solution for your needs.

Hello!
I have experience in processing large datasets and I am ready to create a system for you based on SQL and Python. I will set up automatic loading of new files so that you can update the database yourself with one click without my assistance. In the end, you will receive a fast tool for analysis and instructions for it.
Please let me know if all 20+ files have the same column structure or if they differ depending on the period? Thank you!

Hello!
I have experience in building similar pipelines and analytical dashboards. I can propose an optimal architecture where new files are added without the involvement of a developer, as you want, and the data is automatically consolidated and updates the dashboards. I will immediately lay the groundwork for scalability for further modeling.
Feel free to reach out!

Hello
I have completed a similar task, 2 daily reports with over 200,000 rows, imported into a database (a convenient uploader, just upload the file from the PC and that's it, without complicated actions), the backend combines these 2 reports. We display all of this in the Metabase dashboard for analysis.
What I propose
Data consolidation
Combining all Excel files into a single structure (essentially — a centralized database, not a "heavy" Excel).
Cleaning and unifying fields: date formats, column names, data types, duplicates, gaps.
Building a database for analysis
Creating an analytical model (tables + relationships) for quick slices and filtering by parameters.
Preparing "pivot" tables/views for modeling and further analysis.
Analytics in Metabase
Connecting Metabase to the database.
Setting up ready-made dashboards, filters, segments, drill-down analysis.
Query templates for data selection "in 2 clicks."
Updates without a developer
A simple process for adding new files (through a folder/import) is set up.
Automatic or semi-automatic data updates according to instructions for your team.
Documentation + brief user training.
Result for you
A single source of truthful data instead of dozens of Excels.
Quick analytics of large volumes without "file crashes."
A ready tool for modeling, reporting, and decision-making.

Good day. I am free now, I can start immediately.
20 files × 200k+ rows. I suggest transferring the data to PostgreSQL and creating a simple web interface: uploading new files with a button, filters, and pivot tables — to work with the data without a developer. If needed — backups and replication.
Clarification: is the structure of all files the same? Which analysis parameters are the most important?

Hello! I have extensive experience working with large datasets (Big Data) in Python.
Your volume (4 million+ rows) is too heavy for regular Excel, so I propose an automated solution based on Python + PostgreSQL:
1. A script will automatically gather all your Excel files into a single fast database.
2. You will be able to add new files to the folder and update the database with the press of a button, no developer needed for this.
3. I will set up a convenient tool for querying and pivot tables (Power BI or a simple web interface in Python), where the data will fly.
I am ready to discuss the structure of your tables and suggest the optimal architecture option!
Budget: 3000 UAH Deadline: 30 days
I can create a database, or rather process files using Borland Delphi. It will be a practical and convenient program for viewing and analyzing file searches. The program will only be in gray color, as the focus is on practicality and performance rather than design.

Good day
My name is Dmytro, I represent the company King Kong Lab
I can build a convenient database and a tool for analyzing large Excel files without "crashes" and manual work
What I will do
I will combine all files (20+ with 200k rows each) into a single structure
I will clean and normalize the data
I will build a database (PostgreSQL / BigQuery or another optimal option)
I will create a convenient tool for analysis (dashboards / filters / pivot tables)
Most importantly
I will set up simple data updates
so you can add new files yourself (via Excel / Google Sheets / import) without involving a developer
I can also
set up automatic updates
add quick filters and selections for your tasks
prepare data for further modeling

Good day. I can implement a solution for you to consolidate 20+ Excel files with over 200,000 rows, build a single database, and create an analytical tool for selection, modeling, and working with pivot tables. For such a volume of data, I would recommend not just one large Excel file, but a more stable solution based on a database + a user-friendly interface for updating and analysis, so that the system works quickly and without Excel limitations.

Good day. With such a volume of data, it is definitely necessary to use an industrial database. I would choose MSSQL. The database should process data in seconds. Excel will not handle it. Moreover, MSSQL already has an MS SQL Report Server. Reports can already be built. It is also necessary to implement automatic (semi-automatic) data loading. I can create such a utility; the programming language does not matter (1C, Delphi, C#...). At the same time, PowerBI can be used. However, it is slower than MS SQL Report Server. Everything depends on the requirements. Just digital reports, or visualization in the form of graphs.
