Getting Started: Installation and Setup

Getting started with Aspose.Cells.LowCode is refreshingly simple. First, install the package via NuGet:

Install-Package Aspose.Cells

That’s it! The library is self-contained with no external dependencies, making deployment a breeze.

Excel Format Conversion Made Simple

Let’s dive into some practical examples of how Aspose.Cells.LowCode simplifies common Excel operations.

Converting Excel to CSV

Converting Excel files to CSV format is one of the most common tasks developers face. With Aspose.Cells.LowCode, it’s remarkably straightforward:

using Aspose.Cells.LowCode;

// Simple Excel to CSV conversion
var loadOptions = new LowCodeLoadOptions { InputFile = "quarterly_sales.xlsx" };
var saveOptions = new LowCodeTextSaveOptions { 
    OutputFile = "quarterly_sales.csv",
    Format = TextFormat.Csv
};

var converter = new TextConverter(loadOptions, saveOptions);
converter.Convert();

Need a custom delimiter? No problem:

var saveOptions = new LowCodeTextSaveOptions { 
    OutputFile = "quarterly_sales.csv",
    Format = TextFormat.Csv,
    Delimiter = ';'  // Use semicolon instead of comma
};

Exporting Excel to JSON

JSON is the lingua franca of web APIs. Converting your Excel data to JSON is incredibly simple:

using Aspose.Cells.LowCode;

var loadOptions = new LowCodeLoadOptions { InputFile = "product_catalog.xlsx" };
var jsonOptions = new LowCodeJsonSaveOptions { 
    OutputFile = "product_catalog.json",
    IndentOutput = true
};

var jsonConverter = new JsonConverter(loadOptions, jsonOptions);
jsonConverter.Convert();

This transforms each row in your Excel sheet into a JSON object, perfect for API responses or data processing pipelines.

Generating HTML from Excel Spreadsheets

Need to display Excel data on a website? The HTML conversion is equally straightforward:

using Aspose.Cells.LowCode;

var loadOptions = new LowCodeLoadOptions { InputFile = "financial_report.xlsx" };
var htmlOptions = new LowCodeHtmlSaveOptions { 
    OutputFile = "financial_report.html",
    ExportImagesAsBase64 = true  // Embeds images directly in the HTML
};

var htmlConverter = new HtmlConverter(loadOptions, htmlOptions);
htmlConverter.Convert();

Creating PDFs from Excel Files

PDF generation has traditionally been complex, but Aspose.Cells.LowCode makes it surprisingly simple:

using Aspose.Cells.LowCode;

var loadOptions = new LowCodeLoadOptions { InputFile = "annual_report.xlsx" };
var pdfOptions = new LowCodePdfSaveOptions { 
    OutputFile = "annual_report.pdf",
    Compliance = PdfCompliance.PdfA1b,  // For archival purposes
    EmbedFonts = true
};

var pdfConverter = new PdfConverter(loadOptions, pdfOptions);
pdfConverter.Convert();

Exporting Excel Sheets as Images

Sometimes you need a visual representation of your Excel data. Generating images is just as easy:

using Aspose.Cells.LowCode;

var loadOptions = new LowCodeLoadOptions { InputFile = "sales_dashboard.xlsx" };
var imageOptions = new LowCodeImageSaveOptions { 
    OutputDirectory = "dashboard_images/",
    ImageFormat = ImageFormat.Png,
    ScaleFactor = 2.0  // Higher resolution for clearer images
};

var imageConverter = new ImageConverter(loadOptions, imageOptions);
imageConverter.Convert();

Securing Excel Files with Password Protection

Data security is paramount in today’s world. Aspose.Cells.LowCode makes protecting sensitive Excel files remarkably simple:

using Aspose.Cells.LowCode;

// Define a simple protection provider
public class SimpleProtectionProvider : AbstractLowCodeProtectionProvider
{
    private readonly string openPwd, writePwd;

    public SimpleProtectionProvider(string openPwd, string writePwd)
    {
        this.openPwd = openPwd;
        this.writePwd = writePwd;
    }

    public override string GetOpenPassword() => openPwd;
    public override string GetWritePassword() => writePwd;
}

// Apply password protection
var loadOptions = new LowCodeLoadOptions { InputFile = "financial_data.xlsx" };
var saveOptions = new LowCodeSaveOptions { 
    SaveFormat = SaveFormat.Xlsx, 
    OutputFile = "financial_data_protected.xlsx" 
};
var provider = new SimpleProtectionProvider("OpenSecure123", "EditSecure456");

SpreadsheetLocker.Process(loadOptions, saveOptions, provider);

This applies two levels of protection:

A password required to open the file
A separate password required to edit the file

Removing protection is equally straightforward:

// Remove password protection
var removeProvider = new SimpleProtectionProvider(string.Empty, string.Empty);
SpreadsheetLocker.Process(
    new LowCodeLoadOptions { InputFile = "financial_data_protected.xlsx" },
    new LowCodeSaveOptions { 
        SaveFormat = SaveFormat.Xlsx, 
        OutputFile = "financial_data_unlocked.xlsx" 
    },
    removeProvider
);

Real-World Scenarios and Advanced Usage

Let’s look at some more complex scenarios where Aspose.Cells.LowCode shines.

Batch Processing Multiple Excel Files

Need to convert an entire directory of Excel files to CSV? Here’s how simple it is:

using Aspose.Cells.LowCode;
using System.IO;

string[] excelFiles = Directory.GetFiles("input_folder", "*.xlsx");

foreach (string file in excelFiles)
{
    string filename = Path.GetFileNameWithoutExtension(file);
    
    var loadOptions = new LowCodeLoadOptions { InputFile = file };
    var saveOptions = new LowCodeTextSaveOptions { 
        OutputFile = $"output_folder/{filename}.csv",
        Format = TextFormat.Csv
    };

    var converter = new TextConverter(loadOptions, saveOptions);
    converter.Convert();
}

Converting Excel API Responses to PDF Reports

When working with APIs that return Excel data, you might need to generate PDF reports:

using Aspose.Cells.LowCode;
using System.Net.Http;
using System.IO;

// Download Excel file from API
using (var client = new HttpClient())
{
    byte[] excelData = await client.GetByteArrayAsync("https://api.example.com/reports/latest");
    File.WriteAllBytes("temp_report.xlsx", excelData);
    
    // Convert to PDF
    var loadOptions = new LowCodeLoadOptions { InputFile = "temp_report.xlsx" };
    var pdfOptions = new LowCodePdfSaveOptions { 
        OutputFile = "latest_report.pdf",
        EmbedFonts = true
    };

    var pdfConverter = new PdfConverter(loadOptions, pdfOptions);
    pdfConverter.Convert();
    
    // Clean up temp file
    File.Delete("temp_report.xlsx");
}
