  • Iterate through the results to highlight the cells by setting a fill color through CellRange.Style.Color property.
  • Save the workbook using Workbook.SaveToFile() method.
  • Python
Python
from spire.xls import *

# Create an instance of Workbook
workbook = Workbook()

# Load an Excel file
workbook.LoadFromFile("Sample.xlsx")

# Get the first worksheet
sheet = workbook.Worksheets.get_Item(0)

# Find the data to be highlighted
cellRanges = sheet.FindAllString("Urgent", False, True)

# Iterate through the found ranges
for cellRange in cellRanges:
    # Highlight the data
    cellRange.Style.Color = Color.get_LightYellow()

# Save the workbook
workbook.SaveToFile("output/FindHighlightDataExcel.xlsx")
workbook.Dispose()

Extract Text from a Textbox in Word

Using Spire.Doc for Python, you can access a specific text box in a document by utilizing the Document.TextBoxes[index] property. After retrieving the text box, you can iterate through its child objects to identify whether each one is a paragraph or a table. If the object is a paragraph, you can retrieve its text using the Paragraph.Text property. In cases where the object is a table, you will need to loop through each cell to extract text from every individual cell within that table.

The steps to extract text from a text box in a Word document are as follows:

  • Create a Document object.
  • load a Word file by using Document.LoadFromFile() method.
  • Access a specific text box using Document.TextBoxes[index] property.
  • Iterate through the child objects within the text box.
  • Determine if a child object is a paragraph. If it is, retrieve the text from the paragraph using Paragraph.Text property.
  • Check if a child object is a table. If so, iterate through the cells in the table to extract text from each cell.
  • Python
from spire.doc import *
from spire.doc.common import *

# Create a Document object
document = Document()

# Load a Word file
document.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx")

# Get a specific textbox
textBox = document.TextBoxes[0]

with open('ExtractedText.txt','w') as sw:

    # Iterate through the child objects in the textbox
    for i in range(textBox.ChildObjects.Count):

        # Get a specific child object    
        object = textBox.ChildObjects.get_Item(i)

        # Determine if the child object is paragraph
        if object.DocumentObjectType == DocumentObjectType.Paragraph:

            # Write paragraph text to txt file
            sw.write((object if isinstance(object, Paragraph) else None).Text + "\n")

        # Determine if the child object is table
        if object.DocumentObjectType == DocumentObjectType.Table:
            table = object if isinstance(object, Table) else None
            for i in range(table.Rows.Count):
                row = table.Rows[i]
                for j in range(row.Cells.Count):
                    cell = row.Cells[j]
                    for k in range(cell.Paragraphs.Count):
                        paragraph = cell.Paragraphs.get_Item(k)

                        # Write paragrah text of a specific cell to txt file
                        sw.write(paragraph.Text + "\n")

# Dispose resources
document.Dispose()

Extract Text from a Textbox in Word in Java

With Spire.Doc for Java, you can access a specific text box in a document using the Document.getTextBoxes().get() method. You can then iterate through the child objects of the text box to check if each one is a paragraph or a table. For paragraphs, retrieve the text using the Paragraph.getText() method. For tables, loop through the cells to extract text from each cell.

Here are the steps to extract text from a text box in a Word document:

  • Create a Document object.
  • Load a Word file using Document.loadFromFile() method.
  • Access a specific text box using Document.getTextBoxes().get() method.
  • Iterate through the child objects of the text box.
  • Check if a child object is a paragraph. If so, use Paragraph.getText() method to get the text.
  • Check if a child object is a table. If so, use extractTextFromTable() method to retrieve the text from the table.
  • Java
import com.spire.doc.*;
import com.spire.doc.documents.DocumentObjectType;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.TextBox;

import java.io.FileWriter;
import java.io.IOException;

public class ExtractTextFromTextbox {

    public static void main(String[] args) throws IOException {

        // Create a Document object
        Document document = new Document();

        // Load a Word file
        document.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Get a specific textbox
        TextBox textBox = document.getTextBoxes().get(0);

        // Create a FileWriter to write extracted text to a txt file
        FileWriter fileWriter = new FileWriter("Extracted.txt");

        // Iterate though child objects of the textbox
        for (Object object: textBox.getChildObjects()) {

            // Determine if the child object is a paragraph
            if (((DocumentObject) object).getDocumentObjectType() == DocumentObjectType.Paragraph) {

                // Write paragraph text to the txt file

Java: Extract or Update Textboxes in Word

Update a Textbox in Word in Java

To modify a text box, first remove its existing content using TextBox.getChildObjects.clear() method. Then, create a new paragraph and assign the desired text to it.

Here are the steps to update a text box in a Word document:

  • Create a Document object.
  • Load a Word file using Document.loadFromFile() method.
  • Get a specific textbox using Document.getTextBoxes().get() method.
  • Remove existing content of the textbox using TextBox.getChildObjects().clear() method.
  • Add a paragraph to the textbox using TextBox.getBody().addParagraph() method.
  • Add text to the paragraph using Paragraph.appendText() method.
  • Save the document to a different Word file.
  • Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.TextBox;
import com.spire.doc.fields.TextRange;

public class UpdateTextbox {

    public static void main(String[] args) {

        // Create a Document object
        Document document = new Document();

        // Load a Word file
        document.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Get a specific textbox
        TextBox textBox = document.getTextBoxes().get(0);

        // Remove child objects of the textbox
        textBox.getChildObjects().clear();

        // Add a new paragraph to the textbox
        Paragraph paragraph = textBox.getBody().addParagraph();

        // Set line spacing
        paragraph.getFormat().setLineSpacing(15f);

        // Add text to the paragraph
        TextRange textRange = paragraph.appendText("The text in this textbox has been updated.");

        // Set font size
        textRange.getCharacterFormat().setFontSize(15f);

        // Save the document to a different Word file
        document.saveToFile("UpdateTextbox.docx", FileFormat.Docx_2019);

        // Dispose resources
        document.dispose();
    }
}
