如何将提取的文本从PDF格式映射到Excel单元格？

我尝试从PDF中提取文本，并从该文本创buildExcel，我已经使用pdfbox从PDF中提取文本，但现在我试图将它们粘贴到excel细胞结构在pdf中，我有x和y坐标的文本，但我如何将他们映射到Excel单元格？ 首先我已经尝试了一个PDF页面到一个Excel工作表，然后得到所有的对象在一个PDF页面，从Y坐标sorting，并得到如下排名

 private DataTable RankDt(DataTable dt, string fld) { var rankDt = (from row in dt.AsEnumerable() orderby row.Field<float>(fld) select row).CopyToDataTable(); rankDt.Columns.Add(fld+"Rank",typeof(int)); int rank = 1; for (int i = 0; i < rankDt.Rows.Count - 1; i++) { rankDt.Rows[i][fld + "Rank"] = rank; if (rankDt.Rows[i][fld].ToString() != rankDt.Rows[i + 1][fld].ToString()) rank++; } rankDt.Rows[rankDt.Rows.Count - 1][fld + "Rank"] = rank; return rankDt; } 

然后循环到行计数并在Excel中如下所示通过它们

  public void CreateExcelOutputFile(System.Data.DataTable dt, string destinationFileName, string destinationFilePath) { try { Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); Workbook wb = xlApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet ws = (Worksheet)wb.Worksheets[1]; if (dt.Rows.Count > 0) { int rowNo = 1; for (int i = 0; i < dt.Rows.Count - 1; i++) { var dty = (from row in dt.AsEnumerable() orderby row.Field<float>("x") where row.Field<int>("yRank") == rowNo select row); if (dty.Count() == 0) { break; } else { var tbl = dty.CopyToDataTable(); for (int y = 0; y < tbl.Rows.Count; y++) { ws.Cells[rowNo, y+1] = tbl.Rows[y]["text"].ToString(); } } rowNo++; } } wb.SaveAs((destinationFilePath + '\\' + destinationFileName), Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); wb.Close(); } catch (Exception ex) { throw ex; } } 

70％的数据是格式化的，因为它们看起来像PDF，但有些文本没有格式化为pdf

这pdftoexcel网站做得很好，他们如何做这个转换？ 有没有人可以提供一个提示或解决scheme？ 提前致谢

尝试使用这个。

  void ExportTOExcel(System.Data.DataTable dt) { Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel.Workbook xlWorkBook; Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; xlApp = new Microsoft.Office.Interop.Excel.Application(); xlWorkBook = xlApp.Workbooks.Add(misValue); xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); //add data int StartCol = 1; int StartRow = 1; int j = 0, i = 0; //Write Headers for (j = 0; j < dt.Columns.Count; j++) { Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[StartRow, StartCol + j]; myRange.Value2 = dt.Columns[j].HeaderText; } StartRow++; //Write dt content for (i = 0; i < dt.Rows.Count; i++) { for (j = 0; j < dt.Columns.Count; j++) { try { Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[StartRow + i, StartCol + j]; myRange.Value2 = dt[j, i].Value == null ? "" : dt[j, i].Value; } catch { ; } } } Microsoft.Office.Interop.Excel.Range chartRange; Microsoft.Office.Interop.Excel.ChartObjects xlCharts = (Microsoft.Office.Interop.Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing); Microsoft.Office.Interop.Excel.ChartObject myChart = (Microsoft.Office.Interop.Excel.ChartObject)xlCharts.Add(10, 80, 300, 250); Microsoft.Office.Interop.Excel.Chart chartPage = myChart.Chart; chartRange = xlWorkSheet.get_Range("A1", "B" + dt.Rows.Count); chartPage.SetSourceData(chartRange, misValue); chartPage.ChartType = Microsoft.Office.Interop.Excel.XlChartType.xlColumnClustered; xlApp.Visible = true; }
