Export Excel Equations to Other Formats with Python.NET

Sometimes you may need to export Excel formulas to other formats in your code to meet your work requirements. The Aspose.Cells library can meet your needs. The following content explains methods for exporting Excel formulas to other formats.

We have prepared sample code here to help you achieve your goals using Aspose.Cells. Necessary sample files are also provided.

Export Equations as LaTeX Expressions

To export equations in Excel as LaTeX expressions, use the to_latex() method.

The following sample code demonstrates how to use the to_latex() method and insert the generated results into HTML:

Python Code

import os
from aspose.cells import Workbook
from aspose.cells.drawing import TextBox
from aspose.cells.drawing.equations import EquationNode

dir_path = "testcase/data"
workbook = Workbook(os.path.join(dir_path, "Sample_equation.xlsx"))

html_content = [
    "<!DOCTYPE html>",
    "<html lang=\"en\">",
    "<head>",
    "    <meta charset=\"UTF-8\">",
    "    <title>Title</title>",
    "    <script type=\"text/javascript\" async src=\"https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-MML-AM_CHTML\"></script>",
    "    <script type=\"text/x-mathjax-config\">",
    "        MathJax.Hub.Config({",
    "            tex2jax: {",
    "                inlineMath: [['$','$'], ['\\\\(','\\\\)']],",
    "                processEscapes: true",
    "            }",
    "        });",
    "    </script>",
    "</head>",
    "<body>"
]

textboxes = workbook.worksheets[0].text_boxes
text_box = textboxes[0] # Assuming first shape is TextBox
math_node = text_box.get_equation_paragraph().get_child(0)
latex_expression = math_node.to_la_te_x()
html_content.append(f"<p>${latex_expression}$</p>")
html_content.append("</body>")
html_content.append("</html>")

with open("result.html", "w", encoding="utf-8") as f:
    f.write("\n".join(html_content))

Export Equations as MathML Expressions

To export equations in Excel as MathML expressions, use the to_math_ml() method.

The following sample code demonstrates how to use the to_math_ml() method and insert the generated results into HTML:

Python Code

import os
from aspose.cells import Workbook
from typing import List

dir_path = "testcase/data/"
        
workbook = Workbook(os.path.join(dir_path, "Sample_equation.xlsx"))

html_builder = [
    "<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n    <meta charset=\"UTF-8\">\n    <title>Title</title>\n",
    "    <script type=\"text/javascript\" async src=\"https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.7/MathJax.js?config=TeX-MML-AM_CHTML\"></script>\n</head>\n<body>"
]

textboxes = workbook.worksheets[0].text_boxes
text_box = textboxes[0]  # Type inferred as TextBox from ShapeCollection
math_node = text_box.get_equation_paragraph().get_child(0)
html_builder.append(math_node.to_math_ml())
html_builder.append("</body>\n</html>")

html_content = "\n".join(html_builder)

output_path = os.path.join(dir_path, "result.html")
with open(output_path, "w", encoding="utf-8") as file:
    file.write(html_content)
