Sure! Here are the steps to create the Java project in IntelliJ IDEA with Maven as the dependency manager:

1. Open IntelliJ IDEA and go to "File" > "New Project" > "Java" > "Maven" > "Maven Project"
2. Enter a project name, choose "Create from archetype" and select "maven-archetype-quickstart" from the drop-down list.
3. Click "Next" and choose a package and group for the project.
4. Click "Finish" and IntelliJ IDEA will create the project with the default directory structure.
5. You can customize the project structure by adding or removing directories and files as needed.
6. You can then create a Java class that takes in an Excel file as a parameter and converts it to a CSV file using a third-party library such as Apache POI.
7. You can add Maven repository URLs to your project's settings to download and include dependencies that are not available in the default Maven repository.
8. You can also configure the build settings, including the compiler version, to ensure that the project is industry-level.
9. Finally, you can verify the project by running the Maven command "mvn clean package" to compile and package the project into a runnable jar file.

I hope this helps you create your Java project! Let me know if you have any further questions.

To create an industry-level Java project with IntelliJ IDEA and Maven as the dependency manager for converting an Excel file to a CSV file, follow these steps:

1. Install IntelliJ IDEA: If you haven't already, download and install the latest stable version of IntelliJ IDEA from the official website (https://www.jetbrains.com/idea/download/).

2. Set up Maven: IntelliJ IDEA comes with built-in support for Maven. To use Maven, go to File > Settings (on Windows) or Preferences (on macOS), select "Build, Execution, Deployment" > "Build Tools" > "Maven," and ensure that the checkbox for "Enable Maven" is selected.

3. Create a new Maven project: In IntelliJ IDEA, select "File" > "New Project" from the main menu. In the "New Project" dialog box, choose "Maven" as the project type, select "Java" as the language, and click "Next."

4. Configure the project: In the "Project SDK" section, select a JDK version compatible with your project requirements. In the "Group Id" and "Artifact Id" fields, enter unique identifiers for your project (e.g., `com.example.excelcsvconverter` and `excel-csv-converter`, respectively).

5. Add dependencies: To convert Excel files to CSV, you'll need the Apache POI library. Add the following dependency to your project's `pom.xml` file:

   ```xml
   <dependency>
       <groupId>org.apache.poi</groupId>
       <artifactId>poi</artifactId>
       <version>4.1.2</version>
   </dependency>
   ```

   Replace `4.1.2` with the latest stable version of Apache POI.

6. Create a package structure: To maintain an industry-level project structure, create a package hierarchy in your project. For example, you could create a package named `com.example.excelcsvconverter.core` for your core conversion logic.

7. Create a main class: Create a Java class in your project's `core` package (e.g., `ExcelToCsvConverter`) that will handle the conversion process.

8. Implement the conversion logic: Use Apache POI to read the Excel file and write the data to a CSV file. You can find examples and documentation for Apache POI on their official website (https://poi.apache.org/).

9. Run the project: To run your project, right-click on the project in the Project tool window, select "Run 'projectName' (App)," and choose the main class you created in step 7.

10. Test the conversion: Create a sample Excel file and run the project to ensure the conversion works as expected.

Remember to follow best practices for code organization, documentation, and testing to maintain an industry-level project. Good luck!

Sure, I'd be happy to help you with that! Here are the steps to create a Java project in IntelliJ IDEA with Maven as the dependency manager, which can convert an Excel file to a CSV file:

1. Install IntelliJ IDEA and Maven on your computer if you haven't already. You can download them from the official websites:
* IntelliJ IDEA: <https://www.jetbrains.com/idea/>
* Maven: <https://maven.apache.org/download.cgi>
2. Create a new project in IntelliJ IDEA by selecting "New Project" from the start screen or by pressing Shift + Ctrl + N (Windows/Linux) or Command + N (Mac).
3. In the "New Project" dialog box, select "Maven" as the project type and click "Next".
4. In the "Maven Project" dialog box, enter the following details:
* Group Id: com.example
* Artifact Id: excel-to-csv
* Version: 1.0-SNAPSHOT
* Package name: com.example.exceltocsv
* Description: A Java program to convert Excel files to CSV files

Click "Next" and then click "Finish".
5. Create a new folder structure for your project. I recommend creating the following folders:
* src/main/java
* src/main/resources
* src/test/java
* target

You can create these folders by clicking on the " Michel keep clicked" button in the top right corner of the IntelliJ IDEA window and selecting "New | Folder" or by using the keyboard shortcut Ctrl + Shift + N (Windows/Linux) or Command + Shift + N (Mac).
6. In the "src/main/java" folder, create a new Java class called "ExcelToCsv.java". This class will contain the code for converting the Excel file to a CSV file.
7. In the "src/main/resources" folder, create a new Excel file called "input.xlsx". This file will be used as input for the conversion.
8. In the "src/test/java" folder, create a new Java class called "ExcelToCsvTest.java". This class will contain test cases for the "ExcelToCsv" class.
9. In the "target" folder, create a new folder called "csv". This folder will contain the output CSV file.
10. Open the "ExcelToCsv.java" file and add the following code:
```java
package com.example.exceltocsv;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.List;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class ExcelToCsv {
    public static void main(String[] args) {
        File inputFile = new File("src/main/resources/input.xlsx");
        File outputFile = new File("target/csv/output.csv");
        
        try (FileInputStream fis = new FileInputStream(inputFile)) {
            HSSFWorkbook workbook = new HSSFWorkbook(fis);
            HSSFSheet sheet = workbook.getSheetAt(0);
            List<String[]> data = new ArrayList<>();
            
            for (HSSFRow row : sheet) {
                HSSFCell cell = row.getCell(0);
                String value = cell.getStringCellValue();
                data.add(new String[]{value});
            }
            
            try (FileWriter writer = new FileWriter(outputFile)) {
                for (String[] row : data) {
                    for (String cell : row) {
                        writer.write(cell + ",");
                    }
                    writer.write("\n");
                }
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}
```
This code uses the Apache POI library to read an Excel file and converts it to a CSV file. It assumes that the Excel file has only one sheet and that the first row contains the column headers.
