        // Ensure directories exist
        if (!System.IO.Directory.Exists(documentDirectory))
            System.IO.Directory.CreateDirectory(documentDirectory);

        if (!System.IO.Directory.Exists(outputDirectory))

Implementation Guide

Convert PNG to XLSX

Follow these steps to convert a PNG image to an Excel spreadsheet:

Load the Source PNG File

Load your source PNG file using GroupDocs.Conversion:

using (var converter = new Converter(Path.Combine(documentDirectory, "sample.png")))
{
    // Conversion process will be defined here
}

This step initializes the conversion by loading the PNG image.

Define Conversion Options for XLSX Format

Specify the desired format using conversion options:

var options = new SpreadsheetConvertOptions();

SpreadsheetConvertOptions() configures parameters for converting files into spreadsheet formats like XLSX.

Convert and Save the Output to an XLSX File

Perform the conversion and save the output file:

string outputFile = Path.Combine(outputDirectory, "png-converted-to.xlsx");
converter.Convert(outputFile, options);

This code converts the PNG into an XLSX file and saves it in your specified directory.

Setup Document and Output Directories

Efficiently manage directories to ensure smooth operations:

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

// Ensure the existence of the document directory
if (!Directory.Exists(documentDirectory))
{
    Directory.CreateDirectory(documentDirectory);
}

// Ensure the existence of the output directory
if (!Directory.Exists(outputDirectory))
{
    Directory.CreateDirectory(outputDirectory);
}

Practical Applications

GroupDocs.Conversion for .NET can be applied in various scenarios:

  1. Data Extraction: Convert images containing data into spreadsheets for easier manipulation.
  2. Reporting: Transform graphical reports into editable formats for analysis.
  3. Archiving: Archive image-based documents as structured Excel files for storage.

Performance Considerations

To optimize performance, manage resources efficiently:

  • Handle only necessary file conversions at a time.
