FastGantt

FastGantt is an AI gantt chart maker tool that turns a spreadsheet or a text brief into a shareable Gantt timeline. FastGantt converts Excel files or plain text descriptions into Gantt charts in the browser, with Day, Week and Month views and export to PNG or Excel.

FastGantt is a browser based tool for turning planning material you already have into a visual project timeline. Two entry points cover most situations: upload an .xlsx or .xls file and map its columns, or describe the project in plain language and let the AI draft the schedule. There is no account wall at the start, so a first chart can be produced in the time it takes to open a spreadsheet. The Excel route is the more controlled one. After the upload, a guided flow asks you to confirm Task, Start Date and End Date (required), with Progress as an optional field. Smart mapping recognises common header names and date formats, which cuts down on cleanup when files arrive from different teammates or templates. Once the data is mapped, the chart renders and can be reviewed in Day, Week or Month views, which is where sequence, overlap, milestone placement and dependencies get checked before anyone else sees the plan. The text route suits earlier stage work: rough notes, requirements or a first draft become a structured draft timeline, and a bonus mode lets you upload a messy Excel or TXT file and combine its contents with a prompt for the AI to parse. Output is deliberately split in two directions. PNG export serves slides, documents and client updates, while Excel export keeps the timeline editable for whoever owns ongoing planning. That dual output is the practical argument for the tool: one chart can serve both the presentation audience and the execution audience without being rebuilt. It fits teams that need a weekly timeline refreshed from spreadsheet data rather than a full project management suite, and individuals who want a chart quickly without learning chart formatting or writing formulas. Anyone needing resource allocation, budget tracking, collaboration or task assignment should look at dedicated project platforms instead. FastGantt is a converter and a drafting aid, not a system of record. The Pro plan at $7.9 per month adds HD PNG export at 3x and unlimited AI text to Gantt, and a 30 credit pack at $4.9 is available for occasional use.
