Indented Dependency Gantt Chart

I have a project schedule that now needs to be presented as a clean, professional Gantt chart. Every task must appear in proper chronological order, and the predecessor / successor relationships should be shown through indented task lists rather than connecting arrows or colour blocks.

Core requirements
• Convert my existing task list into a Gantt chart.
• Display task dependencies through indentation.
• Highlight any timing conflicts you spot while building the chart.

Please deliver the Gantt in an editable file (native software file) plus a PDF snapshot for quick sharing. If you normally work in Microsoft Project, Excel, Smartsheet, or another dedicated tool, that’s fine—just let me know which format you’ll use so I can open and update it later.
