The Excel Gantt chart alternative.
Stop maintaining a Gantt chart by hand. Describe your project and Ganttastic’s AI builds a real, editable Gantt with live dependencies — and still exports back to Excel when you need the spreadsheet.
Import your spreadsheet. Export back any time. No lock-in.
The honest version
Excel is free and familiar. The cost is the upkeep.
For a quick one-off list, a spreadsheet is fine — you already have it and already know it. The cost shows up the moment the project is real: every dependency is manual, every scope change is a rebuild, and every hour goes into maintaining the sheet instead of managing the work. That’s the moment Ganttastic pays off.
Why spreadsheets slip
The trouble with Gantt charts in Excel.
Dependencies are manual
Nothing moves when a date slips. You re-drag every downstream cell by hand — or you don't, and the plan quietly goes stale.
Every scope change is a rebuild
Add a phase or reorder tasks and you're reformatting rows, colours, and formulas instead of managing the project.
No critical path, no baselines
A grid of coloured cells is a picture of a schedule — not a live plan that tells you what actually moves the deadline.
It looks unpolished when shared
A spreadsheet emailed to a client or exec rarely reads as a credible, stakeholder-ready plan.
How Ganttastic works
A live plan, not a grid of cells.
Describe your project
Paste a brief or a plain-English description — or import the Excel/CSV plan you already have. No formatting, no formulas.
Ganttastic generates the plan
The AI drafts tasks, phases, milestones, dependencies, and dates as a real Gantt — dependencies that reflow when a date changes, not cells you re-colour.
Edit, share and export
Refine it, share a live link, and export back to Excel, CSV, PDF, or PNG whenever you need. No lock-in.
Keep Excel in the loop
You’re upgrading the workflow, not leaving your files.
Import the Excel or CSV plan you already have, let the AI turn it into a live Gantt, and export back to Excel, CSV, PDF, or PNG whenever the spreadsheet is what someone needs. No lock-in, ever.
