Implementation Guide

Extracting Text as HTML from Excel

Overview

This feature allows you to convert the content of an Excel file into HTML format, preserving its structure and formatting.

Step-by-Step Guide

Initialize Parser
var documentPath = "YOUR_DOCUMENT_DIRECTORY\sample.xlsx";
using (Parser parser = new Parser(documentPath))
{
    // Proceed with text extraction.
}

Explanation: We initialize the Parser object, pointing it to the Excel file.

Configure Extraction Options
FormattedTextOptions options = new FormattedTextOptions(FormattedTextMode.Html);

Explanation: The FormattedTextOptions specifies that we want the output in HTML format. This is crucial for preserving the visual structure of your data.

Extract and Read Content
using (TextReader reader = parser.GetFormattedText(options))
{
    string htmlContent = reader.ReadToEnd();
    // Now, 'htmlContent' holds your Excel data as HTML.
}

Explanation: The GetFormattedText method retrieves the document’s content in the specified format. We read it entirely into a string for further processing.
