+The Virtual Classes Attendance Automation System is a web-based application developed using Flask, a Python web framework, to automate the process of generating attendance reports for virtual classes. This system allows users to upload two CSV files containing student information and attendance records, specify a minimum duration threshold for attendance, and generate a detailed report based on the provided criteria.
+## Deployment
+
+Check out the live deployment of this project [here](https://virtual-classes-attendance-automation.onrender.com).
+
+Key features of the system include:
+File Upload: Users can upload CSV files containing student information (`students_file`) and attendance records (`attendance_file`) directly through the web interface.
+Threshold Setting: The system allows users to specify a minimum duration threshold (in seconds) for considering a student's attendance as valid. This threshold helps filter out short attendance durations.
+Data Processing: Upon form submission, the system processes the uploaded CSV files, converts the 'Time in Call' duration to total seconds, and filters the attendance data based on the specified threshold.
+Data Merge and Reporting: The system merges the filtered attendance data with student information based on matching names. It then generates a report containing relevant details such as roll number, student name, and total duration of attendance in hours, minutes, and seconds format.
+User Interaction: After generating the report, users can view the attendance details in a formatted HTML table (`report.html`). The report page includes a button that allows users to reset and return to the initial form (`index.html`) for further processing.
+This system streamlines the attendance tracking process for virtual classes, providing educators and administrators with a convenient tool to analyze student participation and ensure accurate attendance records. The use of Flask enables rapid development and deployment of the web application, making it accessible and user-friendly for both teachers and students.
+By leveraging Python's pandas library for data manipulation and Flask for web development, the Virtual Classes Attendance Automation System offers a practical solution to enhance efficiency in managing virtual class attendance.
