Generate HTML reports from data

Written by

Computer Science

To generate HTML reports from data, you can use Python along with libraries like pandas for data manipulation and basic HTML/CSS for structuring the report. Here’s a simple yet flexible example:

Sample Code to Generate HTML Reports from Data

python
import pandas as pd

# Sample data (you can replace this with any DataFrame)
data = {
    'Name': ['Alice', 'Bob', 'Charlie'],
    'Department': ['HR', 'Engineering', 'Marketing'],
    'Salary': [50000, 70000, 60000]
}
df = pd.DataFrame(data)

# Generate basic HTML with styling
html_content = f"""
<html>
<head>
    <title>Employee Report</title>
    <style>
        body {{
            font-family: Arial, sans-serif;
            margin: 40px;
        }}
        h1 {{
            color: #333;
        }}
        table {{
            border-collapse: collapse;
            width: 100%;
            margin-top: 20px;
        }}
        th, td {{
            border: 1px solid #ccc;
            padding: 8px;
            text-align: left;
        }}
        th {{
            background-color: #f2f2f2;
        }}
        tr:nth-child(even) {{
            background-color: #f9f9f9;
        }}
    </style>
</head>
<body>
    <h1>Employee Salary Report</h1>
    {df.to_html(index=False, border=0)}
</body>
</html>
"""

# Save the report to an HTML file
with open("employee_report.html", "w") as file:
    file.write(html_content)

print("HTML report generated successfully.")

Explanation:

pandas.DataFrame.to_html() generates an HTML table from the DataFrame.
Inline CSS is used for styling the HTML for readability.
The final output is saved as employee_report.html.

Optional Enhancements:

Use jinja2 for template-based HTML generation.
Add charts using libraries like plotly, matplotlib, or embed JavaScript libraries like Chart.js.
Automate email sending with the report using smtplib.

Let me know if you want an advanced version with charts or interactivity.
