DocumentTextExtractor

DocumentTextExtractor

Simple C# library for extracting text and metadata from .docx, .pptx, and .xlsx files

DocumentTextExtractor provides simple methods for extracting text and metadata from .docx, .pptx, and .xlsx files.

New in v1.0.x

• Initial release
• Support for docx, pptx, xlsx, and pdf
• Contextual extraction for pptx, xlsx

Disclaimer

This library has been tested on a limited set of documents. It is highly likely that documents exist this from which the library, in its current state, cannot extract text.

The PDF implementation relies upon PDFSharp and PDFPlumber. The latter is written in Python and requires that you have installed Python and used pip to install the pdfplumber package.

Simple Examples

Refer to the Test project for a full example.

using DocumentTextExtractor;

void Main(string[] args)
{
  using (DocxTextExtractor docx = new DocxTextExtractor("./temp/", "mydocument.docx"))
  {
    string docxText = docx.ExtractText();
    Dictionary<string, string> docxMetadata = docx.ExtractMetadata();
  }

  using (PptxTextExtractor pptx = new PptxTextExtractor("./temp/", "mypresentation.pptx"))
  {
    string pptxText = pptx.ExtractText();
    Dictionary<string, string> pptxMetadata = pptx.ExtractMetadata();
  }

  using (XlsxTextExtractor xlsx = new XlsxTextExtractor("./temp/", "myspreadsheet.xlsx"))
  {
    string xlsxText = xlsx.ExtractText();
    Dictionary<string, string> xlsxMetadata = xlsx.ExtractMetadata();
  }

  using (PdfTextExtractor pdf = new PdfTextExtractor("myfile.pdf"))
  {
    string pdfText = pdf.ExtractText();
    Dictionary<string, string> pdfMetadata = pdf.ExtractMetadata();
  }
}

Contextual Extraction

For certain document types (e.g. pptx and xlsx) text can be extracted with an identifier for the slide or sheet number associated with the document.

using (PptxTextExtractor pptx = new PptxTextExtractor("./temp/", "mypresentation.pptx"))
{
  IEnumerable<KeyValuePair<int, string>> slideContent = pptx.ExtractTextBySlide();
  foreach (KeyvaluePair<int, string> kvp in slideContent)
  {
    Console.WriteLine("Slide " + kvp.Key + ": " + kvp.Value);
  }
}

using (XlsxTextExtractor xlsx = new XlsxTextExtractor("./temp/", "mypresentation.pptx"))
{
  IEnumerable<KeyValuePair<int, string>> sheetContent = xlsx.ExtractTextBySheet();
  foreach (KeyvaluePair<int, string> kvp in sheetContent)
  {
    Console.WriteLine("Sheet " + kvp.Key + ": " + kvp.Value);
  }
}
