DocumentTextExtractor provides simple methods for extracting text and metadata from .docx, .pptx, and .xlsx files.
- Initial release
- Support for
docx
,pptx
,xlsx
, andpdf
- Contextual extraction for
pptx
,xlsx
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.
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();
}
}
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);
}
}
