Source: https://extractpdf4j.github.io/ExtractPDF4J/how-it-works/stream

Use StreamParser to extract tables from specific pages of a text-based PDF. This example parses pages 1-3 of 'statement.pdf' and prints the first table as CSV.

```java
import com.extractpdf4j.helpers.Table;
import com.extractpdf4j.parsers.StreamParser;

import java.util.List;

public class StreamExample {
    public static void main(String[] args) throws Exception {
        List<Table> tables = new StreamParser("statement.pdf")
                .pages("1-3")
                .parse();

        if (!tables.isEmpty()) {
            System.out.println(tables.get(0).toCSV(','));
        }
    }
}
```

--------------------------------

### CSV Conversion and Writing

Source: https://extractpdf4j.github.io/ExtractPDF4J/api/extractor

Explains how to convert extracted tables to CSV format and write them to disk.

```APIDOC
## CSV conversion

Once a `Table` is returned, a common next step is converting it to CSV:
```java
table.toCSV(',')
```

This is useful for:
  * quick inspection
  * local validation
  * downstream file generation
  * pipeline handoff

## Writing CSV to disk

```java
import com.extractpdf4j.helpers.Table;
import com.extractpdf4j.parsers.StreamParser;

import java.nio.file.Files;
import java.nio.file.Path;
import java.util.List;

public class CsvWriteExample {
    public static void main(String[] args) throws Exception {
        List<Table> tables = new StreamParser("report.pdf")
                .pages("1")
                .parse();

        if (!tables.isEmpty()) {
            Files.writeString(Path.of("out.csv"), tables.get(0).toCSV(','));
        }
    }
}
```
```

--------------------------------

### Extractor Usage Pattern

Source: https://extractpdf4j.github.io/ExtractPDF4J/api/extractor

Demonstrates the typical workflow for using ExtractPDF4J parsers: instantiate, configure, parse, and process results.

```APIDOC
## Extractor Usage Pattern

This page covers the common parser usage pattern in ExtractPDF4J. Although there are multiple parser implementations, they are typically used in a similar way:
  1. create a parser instance
  2. configure extraction options
  3. call `parse()`
  4. work with the returned `List<Table>`

### Common construction pattern

A parser is generally created with a PDF path:
```java
new HybridParser("input.pdf")
```

Then you optionally add configuration:
```java
new HybridParser("input.pdf")
    .pages("1-3")
    .dpi(300f)
```

Then you call:
```java
.parse()
```

### Full example

```java
import com.extractpdf4j.helpers.Table;
import com.extractpdf4j.parsers.HybridParser;

import java.util.List;

public class ExtractorExample {
    public static void main(String[] args) throws Exception {
        List<Table> tables = new HybridParser("statement.pdf")
                .pages("1-3")
                .dpi(300f)
                .parse();

        for (Table table : tables) {
            System.out.println(table.toCSV(','));
        }
    }
}
```
```
