Talk to Excel / Talk to SQL: Russian-language chat for working with tabular data

Tabular data lives in Excel, CSV, and SQL databases, but business needs answers fast. Manual pivot tables, formulas, and SQL queries become a constant bottleneck. I propose the development of a Russian-language "Talk to Excel / Talk to SQL" system that allows users to ask questions of their tables and get answers, reports, and charts in minutes.

What does the system provide

• Unified chat interface for Excel/CSV/Google Sheets and SQL databases.
• Russian-language dialogue for managers and analysts without SQL.
• Generation of secure SQL queries with explanations and access control.
• Ready-made reports and visualizations, export to CSV/Excel/BI.
• Audit and Logging all requests for security.

How it works

1. Connect data sources (Excel/CSV/Sheets/SQL).
2. Loading the diagram and configuring role-based access.
3. Users ask questions in Russian.
4. The system builds queries, generates reports and charts.
5. Results are saved and repeated according to schedule.

For whom

• Heads of Analytics and Chief Financial Officers.
• Operational commands and B2B product owners.
• IT integrators who need a secure data showcase.

Business Outcome

• Reduction of report preparation time from hours to minutes.
• Reducing the workload for analysts and SQL developers.
• Transparent audit: who requested what data and when.
• Unified access to Excel and SQL without data duplication.

Stack and deployment

Python/Flask, SQL connectors (PostgreSQL/MySQL/SQLite), Excel/CSV processing, LLM layer, role-based access, logging. Deployment is carried out within the customer's infrastructure (on-premise or cloud).
