XLAM to XLS Conversion

Overview

This feature converts an Excel Add-In file (XLAM) to a standard Excel workbook (XLS), ensuring compatibility with various Microsoft Office versions.

Step 1: Set Up File Paths

Configure your document and output directories using placeholders:

string sourcePath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "source.xlam");
string outputPath = Path.Combine("YOUR_OUTPUT_DIRECTORY", "xlam-converted-to.xls");

Step 2: Load the Source XLAM File

Use GroupDocs.Conversion to load your XLAM file, specifying the path:

using (var converter = new Converter(sourcePath))
{
    // Conversion logic will follow here.
}

Step 3: Define Conversion Options

Specify conversion settings for XLS format using SpreadsheetConvertOptions:

SpreadsheetConvertOptions options = new SpreadsheetConvertOptions { Format = SpreadsheetFileType.Xls };

This configuration ensures the output file is in the desired XLS format.

Step 4: Convert and Save Output

Execute the conversion and save the resultant XLS file:

csv converter.Convert(outputPath, options);

File Path Configuration

Overview

Setting up your file paths correctly is crucial for successful conversions. This feature ensures you have properly defined input and output directories.

Step 1: Define Directories

Establish the directory structure for source and target files:

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

Step 2: Combine Paths

Generate full file paths using Path.Combine:

string sourceFilePath = Path.Combine(documentDirectory, "source.xlam");
string targetFilePath = Path.Combine(outputDirectory, "xlam-converted-to.xls");
