# Consolidated CSV Data Documentation

## Overview
This directory contains a consolidated CSV file (`consolidated_data_simple.csv`) that combines data from multiple individual CSV files in the `sample_data` directory. Each original CSV file is identified by a sheet number and filename prefix in the consolidated file.

## File Structure

### `consolidated_data_simple.csv`
- **Columns**: `[Sheet_Number, Original_File, Original_Column_1, Original_Column_2, ...]`
- **Sheet Numbers**:
  1. `8-Table 1.csv`
  2. `1-Table 1.csv`
  3. `10-Table 1.csv`
  4. `Лист3-Table 1.csv`
  5. `7-Table 1.csv`
  6. `Реестр заявлений на перевод 252-Table 1.csv`
  7. `ТАЙМПАД-Table 1.csv`
  8. `6 -Table 1.csv`
  9. `11-Table 1.csv`
  10. `4 -Table 1.csv`
  11. `3 -Table 1.csv`
  12. `2 -Table 1.csv`
  13. `5 -Table 1.csv`
  14. `9-Table 1.csv`

## Format Details
- Column 1: `Sheet_Number` - The numeric identifier for the original CSV file
- Column 2: `Original_File` - The filename of the original CSV file
- Columns 3+: The original data columns from each CSV file

## Purpose
This consolidated file is designed for AI/ML analysis where each original CSV sheet can be identified by its sheet number, allowing algorithms to treat each original dataset separately while analyzing the combined data.

## Total Records
- Total rows in consolidated file: 3283
- Number of original CSV files consolidated: 15

## Notes
- All files were encoded in UTF-8 to preserve Cyrillic characters
- Some original files may have been skipped if they did not contain student data (e.g., notification texts)
- The consolidation preserves the original row and column structure from each source file
