Extract table data from the PDF

[elmsst]

Is there a table object exposed anywhere within PdfDocument?

I see the PdfTable class documentation, but this all looks like it is geared toward creating a table within a Pdf document.

What would be most useful would be an enumerable table class similar to the one available within word docs.

Is such a thing available through Spire.PDF, and if so, how is it accessed using C#?

Dear elmsst,

Thanks for your inquiry.
Sorry that I am afraid that it is impossible to extract table from the PDF, since the pdf format is just a canvas where text and graphics are placed without any structure information. Theoretically, PDF does not contain explicit table data. It only contains lines and character glyphs which we tend to interpret as tables.

Dear elmsst,

I am glad to inform you that we have supported extracting table data from PDFs.
Welcome to download and test Spire.PDF Pack(Hot Fix) Version:7.10.4.

Code: Select all

PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile(inputPath);
            StringBuilder builder = new StringBuilder();           
            PdfTableExtractor extractor = new PdfTableExtractor(pdf);
            PdfTable[] tableLists = null;
            for (int pageIndex = 0; pageIndex < pdf.Pages.Count; pageIndex++)
            {
                tableLists = extractor.ExtractTable(pageIndex);
                if (tableLists != null && tableLists.Length > 0)
                {
                    foreach (PdfTable table in tableLists)
                    {
                        int row = table.GetRowCount();
                        int column = table.GetColumnCount();
                        for (int i = 0; i < row; i++)
                        {
                            for (int j = 0; j < column; j++)
                            {
                                string text = table.GetText(i, j);
                                builder.Append(text + " ");
                            }
                            builder.Append("\r\n");
                        }
                    }
                }
            }
            File.WriteAllText(outputFile, builder.ToString());
