How to Use

Only one line to convert a Xlsx file to Html with the use of Stream.

XlsxToHtmlConverter.Converter.ConvertXlsx(inputStream, outputStream);

Or to convert with specific ConverterConfig and progress callback.

XlsxToHtmlConverter.Converter.ConvertXlsx(inputStream, outputStream, config, progressCallback);

Convert Local Files

Just use a string of the path to the file instead of a Stream to convert a local Xlsx file.

string filename = @"C:\path\to\file.xlsx";
XlsxToHtmlConverter.Converter.ConvertXlsx(filename, outputStream);

A third optional parameter can be set to decide whether to use a MemoryStream or a FileStream. When set to true, a MemoryStream is used to load the entire file at once instead of reading the file with a FileStream.

Please note that using a MemoryStream will use up significantly more memory, especially for larger files.

XlsxToHtmlConverter.Converter.ConvertXlsx(filename, outputStream, true);

Conversion Configurations

ConverterConfig include flexible and customizable conversion configurations.

In rare cases where the converter is unable to produce the correct stylings, it is suggested to set ConvertStyles to false, which will at least ensure the conversion of all the content with default stylings.

XlsxToHtmlConverter.ConverterConfig config = new XlsxToHtmlConverter.ConverterConfig()
{
    PageTitle = "My Title",
    PresetStyles = XlsxToHtmlConverter.ConverterConfig.DefaultPresetStyles + " body { background-color: skyblue; } table { width: 100%; }",
    ErrorMessage = "An unhandled error occured during the conversion: {EXCEPTION}",
    Encoding = System.Text.Encoding.UTF8,
    BufferSize = 65536,
    ConvertStyles = true,
    ConvertSizes = true,
    ConvertNumberFormats = true,
    ConvertPictures = true,
    ConvertShapes = true,
    ConvertSheetTitles = true,
    ConvertHiddenSheets = false,
    ConvertFirstSheetOnly = false,
    ConvertHtmlBodyOnly = false,
    UseHtmlStyleClasses = true,
    UseHexColors = true,
    RoundingDigits = 2
};

Progress Callback

A progress callback event can be set up with ConverterProgressCallbackEventArgs, where things like ProgressPercent can be used.

EventHandler<XlsxToHtmlConverter.ConverterProgressCallbackEventArgs> progressCallback = ConverterProgressCallback;
private static void ConverterProgressCallback(object sender, XlsxToHtmlConverter.ConverterProgressCallbackEventArgs e)
{
    string info = string.Format("{0:##0.00}% (Sheet {1} of {2} | Row {3} of {4})", e.ProgressPercent, e.CurrentSheet, e.TotalSheets, e.CurrentRow, e.TotalRows);
    string progress = new string('█', (int)(e.ProgressPercent / 2)) + new string('░', (int)((100 - e.ProgressPercent) / 2));
    Console.WriteLine(info + new string(' ', 5) + progress);
}
