**DataDoctor CLI** is a powerful command-line tool for diagnosing and fixing data quality issues in your files instantly. It acts as a doctor for your datasets, healing broken JSON and CSV files with surgical precision.

## 🚀 Installation


### From Crates.io (Recommended)


```bash
cargo install data-doctor-cli
```
*Note: The binary name is `data-doctor`.*

## 📖 Usage


### 1. Validate Data

Check your data for errors without modifying it.

```bash
data-doctor validate data.json
```

### 2. Fix Data

Auto-correct common issues effectively.

```bash
data-doctor fix broken.json --out fixed.json
```

**What it fixes:**
- **JSON**: Trailing commas, missing quotes, single quotes, unclosed brackets, etc.
- **CSV**: Missing columns (padding), extra columns (trimming), type mismatches, boolean normalization.

### 3. The "Doctor" Command

Run a full diagnosis, fix issues, and generate a report in one go.

```bash
data-doctor doctor input.csv --out cleaned.csv --report-json
```

### Options


- `--format <json|csv>`: Manually specify file format (auto-detected by default).
- `--report-json`: Output the validation report in machine-readable JSON format.
- `--schema <file>`: Validate against a custom schema.

## ⚡ Examples


**Fixing a broken JSON file:**
```bash
# Input: { name: 'John', age: 30, }

data-doctor fix user.json --out clean.json
# Output: { "name": "John", "age": 30 }

```

**Fixing CSV column alignment:**
```bash
data-doctor fix data.csv --out fixed.csv
```
