Implementation Guide

Convert MHT File to XLS Format

Overview: This feature allows for seamless conversion of MHT files into Excel (XLS) format using GroupDocs.Conversion.

Step 1: Define Conversion Options

Start by specifying the target format:

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

Here, SpreadsheetConvertOptions is designed for spreadsheet conversions. Setting the Format instructs GroupDocs.Conversion to output in XLS format.

Step 2: Set Output File Path

Determine where your converted file should be saved:

string outputFile = Path.Combine(outputDirectory, "mht-converted-to.xls");

This step ensures the output is stored correctly and can be accessed later.

Step 3: Perform Conversion

Execute the conversion process and save the output file:

converter.Convert(outputFile, options);

The Convert method takes two arguments: the path of the output file and the conversion options. It performs the actual file transformation and saves the result to your specified directory.

Troubleshooting Tips

  • Invalid File Path: Ensure both input and output directories are correctly defined.
  • Conversion Errors: Check if the MHT file is not corrupted and in a readable format for GroupDocs.Conversion.

Practical Applications

  1. Data Analysis Automation: Convert large batches of MHT files into XLS for easier data manipulation and analysis.
  2. Web Scraping Data Storage: Store scraped web pages from HTTP messages (MHT) as structured Excel spreadsheets.
  3. Collaborative Workflows: Share converted datasets with team members who prefer using Excel.

Performance Considerations

  • Optimize File Handling: Process files in memory only when necessary to reduce resource usage.
  • Batch Processing: Convert multiple MHT files simultaneously if possible, to improve efficiency.
  • Memory Management: Dispose of the Converter object properly to free up resources after conversion.
