# CSV Console Table in PowerShell
This PowerShell implementation provides dynamic column type detection and data validation while creating clean, aligned console output - making it ideal for consistent data snapshots and type verification.
## Features
- Dynamically detects and validates column types from CSV data
- Supports multiple data types: Int, Float, Bool, String, and Null
- Creates formatted console tables with proper alignment
- Validates subsequent rows against the detected schema
- Handles duplicate column names with automatic suffixes
- Limits output width with smart string truncation
- Saves output to both console and file
## Example Input CSV ([`default.csv`](default.csv)):
```csv
1,Welcome to dynamic-csv-headers.ps1 Welcome to csv_console_table.ps1,10.00
2,This is a sample data csv file,19.97
3,1st row: set header types,1.99
4,This file headers: 'int *char float *char',11.99
5,Unknown types become `*char/string`,19.97
6,'gcc -o xyz .\csv_processor.c -lm',19.17
7,'.\csv_console_table.ps1',19.84
8,'python -m grip README.md',16.89
9,'.\csv_console_table.ps1' yourfile.csv ,19.97
```
## Example Output
## Usage
- **PowerShell**:
- .\csv_console_table.ps1 .\yourfile.csv (optional)
- **BASH**:
- pwsh csv_console_table.ps1 yourfile.csv (optional)
## Parameters
- DefaultFile: Path to CSV file (default: "default.csv")
- rowLimit: Maximum rows to process (range: 1-1000, default: 10)
## Data Type Detection
- The script automatically detects these column types:
- Int (whole numbers)
- Float (decimal numbers)
- Bool (true/false)
- String (text)
- Null (empty or null values)
## Limitations
- The script assumes the first row contains column headers.
- Duplicate column names are not supported.
- The output width is limited to 120 characters.
## Requirements
- PowerShell 7.0+
- Read access to CSV files
## Purpose
- This PowerShell implementation offers:
- Dynamic type detection and validation
- Clean console output formatting
- Data integrity verification
- Platform independence
- Educational resource for PowerShell scripting practices
## Alternatives
- **PowerShell**:
- Import-Csv "data.csv" | Format-Table
- **BASH**:
- csvcut -c 1,2,3 default.csv
