I perform data clean-up and organization using spreadsheet tools to turn raw data into structured and readable reports.

For example, I worked on webinar attendance data containing raw attendee logs. I cleaned and organized the data to identify:

- Total number of attendees

- Join times

- Latest leave times

- Duplicate entries

- Attendee drop-off points during the webinar

After cleaning the data, I created summary reports and visual graphs for easier analysis. These reports help identify attendee engagement trends and provide useful insights for improving future webinars and events.
