Retrieve structured information for analysis." --- # Extract tables from PDFs and images using C# Nutrient.NET SDK’s (formerly GdPicture.NET) table extraction engine is a native SDK that enables you to recognize tables in an unstructured document or image, parse the information, and export the tables to an external destination like a spreadsheet. It can detect and extract bordered, semi-bordered, and borderless tables in images, scanned PDFs, and digitally born PDFs. As a native SDK, it can be deployed on-premises or embedded in your application, and it works offline, without internet access.

Create a `GdPictureOCR` object and a `GdPicturePDF` object. 2. Select the source document by passing its path to the `LoadFromFile` method of the `GdPicturePDF` object. 3. Select the page from which to extract the table data with the `SelectPage` method of the `GdPicturePDF` object. 4. Render the selected page to a 300 dots-per-inch (DPI) image with the `RenderPageToGdPictureImageEx` method of the `GdPicturePDF` object. 5. Pass the image to the `GdPictureOCR` object with the `SetImage` method. 6. Configure the table extraction process with the `GdPictureOCR` object in the following way: - Set the path to the OCR resource folder with the `ResourceFolder` property. The default language resources are located in `GdPicture.NET 14\Redist\OCR`. For more information on adding language resources, see the [language support](https://www.nutrient.io/guides/dotnet/ocr/language-support.md) guide. - With the `AddLanguage` method, add the language resources that Nutrient.NET SDK uses to recognize text in the image. This method takes a member of the `OCRLanguage` enumeration. For more optional configuration parameters, see the [`GdPictureOCR` class](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14.API~GdPicture14.GdPictureOCR.html). 7. Run the table extraction process with the `RunOCR` method of the `GdPictureOCR` object, and save the result ID in a list. 8. Create a `GdPictureOCR.SpreadsheetOptions` object and configure the output spreadsheet. By default, tables from the same OCR result are saved in the same sheet. To save each table in a different sheet, set the `SeparateTables` property of the `GdPictureOCR.SpreadsheetOptions` object to `true`. For more optional configuration parameters, see the [`GdPictureOCR.SpreadsheetOptions` class](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14.API~GdPicture14.GdPictureOCR+SpreadsheetOptions.html). 9. Save the output in an Excel spreadsheet with the `SaveAsXLSX` method of the `GdPictureOCR` object. This method takes the following parameters: - The list containing the OCR result ID. - The path to the output file. - The `GdPictureOCR.SpreadsheetOptions` object. 10. Release unnecessary resources. The example below extracts table data from the first page of a document and saves the output in an Excel spreadsheet: = ### C# ```csharp using GdPictureOCR gdpictureOCR = new GdPictureOCR(); using GdPicturePDF gdpicturePDF = new GdPicturePDF(); // Load the source document. gdpicturePDF.LoadFromFile(@"C:\temp\source.pdf"); // Select the first page. gdpicturePDF.SelectPage(1); // Render the first page to a 300 DPI image. int imageId = gdpicturePDF.RenderPageToGdPictureImageEx(300, true); // Pass the image to the `GdPictureOCR` object. gdpictureOCR.SetImage(imageId); // Configure the table extraction process. gdpictureOCR.ResourceFolder = @"C:\GdPicture.NET 14\Redist\OCR"; gdpictureOCR.AddLanguage(OCRLanguage.English); // Run the table extraction process and save the result ID in a list. string result = gdpictureOCR.RunOCR(); List resultsList = new List() { result }; // Configure the output spreadsheet. GdPictureOCR.SpreadsheetOptions spreadsheetOptions = new GdPictureOCR.SpreadsheetOptions() { SeparateTables = true }; // Save the output in an Excel spreadsheet. gdpictureOCR.SaveAsXLSX(resultsList, @"C:\temp\output.xlsx", spreadsheetOptions); // Release unnecessary resources. gdpictureOCR.ReleaseOCRResults(); GdPictureDocumentUtilities.DisposeImage(imageId); gdpicturePDF.CloseDocument(); ``` ### VB.NET ```vb Using gdpictureOCR As GdPictureOCR = New GdPictureOCR() Using gdpicturePDF As GdPicturePDF = New GdPicturePDF() ' Load the source document. gdpicturePDF.LoadFromFile("C:\temp\source.pdf") ' Select the first page. gdpicturePDF.SelectPage(1) ' Render the first page to a 300 DPI image.

Import the `GdPicture14` and the `Newtonsoft.Json.Linq` namespaces. 2. Create a `GdPictureOCR` object and a `GdPicturePDF` object. 3. Select the source document by passing its path to the `LoadFromFile` method of the `GdPicturePDF` object. 4. Select the page from which to extract the table data with the `SelectPage` method of the `GdPicturePDF` object. 5.

This method takes a member of the `OCRLanguage` enumeration. 8. Run the OCR process with the `RunOCR` method of the `GdPictureOCR` object. 9. Get the number of tables detected during the OCR process with the `GetTableCount` method of the `GdPictureOCR` object. 10. Create the JSON object that contains the tables on the page and loop through the tables. 11. For each table, get the number of columns and rows with the `GetTableColumnCount` and `GetTableRowCount` methods of the `GdPictureOCR` object. 12. Create the JSON object that contains the rows in the table and loop through the rows. 13. Create the JSON object that contains the cells in the row and loop through the cells. 14. Get the detected value for each cell with the `GetTableCellText` method of the `GdPictureOCR` object and save it in the JSON object. 15. Print the tables to the console in JSON format. 16. Release unnecessary resources. The example below extracts table data from the first page of a document and prints the output to the console in JSON format: = ### C# ```csharp using GdPicture14; using Newtonsoft.Json.Linq;... using GdPictureOCR gdpictureOCR = new GdPictureOCR(); using GdPicturePDF gdpicturePDF = new GdPicturePDF(); // Load the source document. gdpicturePDF.LoadFromFile(@"C:\temp\source.pdf"); // Select the first page. gdpicturePDF.SelectPage(1); // Render the first page to a 300 DPI image. int imageId = gdpicturePDF.RenderPageToGdPictureImageEx(300, true); // Pass the image to the `GdPictureOCR` object. gdpictureOCR.SetImage(imageId); // Configure the OCR process. gdpictureOCR.ResourceFolder = @"C:\GdPicture.NET 14\Redist\OCR"; gdpictureOCR.AddLanguage(OCRLanguage.English); // Run the OCR process. string ocrResultId = gdpictureOCR.RunOCR(); // Create the JSON object that contains the tables on the page and loop through the tables. int tableCount = gdpictureOCR.GetTableCount(ocrResultId); dynamic[] tables = new JObject[tableCount]; for (int tableIndex = 0; tableIndex < tableCount; tableIndex++) { int columnCount = gdpictureOCR.GetTableColumnCount(ocrResultId, tableIndex); int rowCount = gdpictureOCR.GetTableRowCount(ocrResultId, tableIndex); // Create the JSON object that contains the rows in the table and loop through the rows. dynamic[] rows = new JObject[rowCount]; for (int rowIndex = 0; rowIndex < rowCount; rowIndex++) { // Create the JSON object that contains the cells in the row and loop through the cells. dynamic[] cells = new JObject[columnCount]; for (int columnIndex = 0; columnIndex < columnCount; columnIndex++) { cells[columnIndex] = new JObject(); cells[columnIndex].RowIndex = rowIndex; cells[columnIndex].ColumnIndex = columnIndex; // Read the content of the cell and save it in the JSON object. cells[columnIndex].Text = gdpictureOCR.GetTableCellText(ocrResultId, tableIndex, columnIndex, rowIndex); } rows[rowIndex] = new JObject(); rows[rowIndex].Cells = new JArray(cells); } tables[tableIndex] = new JObject(); tables[tableIndex].Rows = new JArray(rows); } dynamic tablesOnPage = new JObject(); tablesOnPage.Tables = new JArray(tables); // Print the tables to the console in JSON format.
