Microsoft Project stores plans in .mpp binary files, but it can export to CSV, Excel, and XML — all formats that can be converted to LoopGantt. This guide covers the two most practical paths: CSV export (simple) and XML export (full fidelity).

Option A — CSV export (quickest)

Step 1 — Export from MS Project

  1. Open your project in Microsoft Project.
  2. Go to File → Export → Save Project as File → Text (Tab Delimited).
  3. In the Export Wizard, choose Task data and select these fields:Name, Duration, Start, Finish, % Complete, Predecessors, Notes, Priority, Outline Level.
  4. Save as .txt (rename to .csv after saving).

Step 2 — Map MS Project columns

MS Project fieldLoopGantt fieldNotes
NameNameNo change
DurationDuration (Days)Strip "days" suffix; round to integer
% CompleteProgress (%)No change (0–100)
PredecessorsDependenciesSee conversion note below
NotesDescriptionNo change
PriorityPriority500=medium, 1000=high, 0=low
Outline LevelPhase / taskLevel 1 = phase; Level 2+ = task

Converting MS Project predecessor notation

MS Project uses row numbers for predecessors (e.g., 3FS means row 3, Finish-to-Start). You need to replace these with task names:

  • 3FS → Task Name from Row 3 (FS)
  • 5SS+2d → Task Name from Row 5 (SS+2)
  • 7FF-1d → Task Name from Row 7 (FF-1)

For large projects, use the AI conversion method below to handle this automatically.

Option B — XML export (full fidelity)

XML export preserves dependency types, lag times, calendar exceptions, and outline structure. It's more complex to parse manually but ideal for AI-assisted conversion.

Step 1 — Export XML from MS Project

  1. Go to File → Save As → Microsoft Project XML Format (*.xml).
  2. Save the file.

Step 2 — Convert XML with AI

MS Project XML is verbose but well-structured. Paste it into an AI with the following prompt:

Convert this Microsoft Project XML export into a LoopGantt project plan JSON.

Rules:
- Tasks with OutlineLevel = 1 become phases (isPhase: true, durationDays: 0)
- Tasks with OutlineLevel >= 2 become regular tasks (isPhase: false)
- Summary tasks (IsSummary = true) always become phases
- Milestones (Milestone = 1 or Duration = 0) → isMilestone: true, durationDays: 0
- Dependency types: 0=FF, 1=FS, 2=SF, 3=SS (map to LoopGantt: FF, FS, SF, SS)
- LinkLag is in tenths of a duration unit (default: days). Divide by 10 to get lag days. If the file uses minutes as the duration unit, divide by 4800 instead
- % Complete → progress field (0–100)
- Priority: 500→medium, 1000→high, 0→low, 100→critical
- Strip phases from the dependencies array (phases cannot have dependencies)

Return only valid LoopGantt JSON. No markdown, no explanation.

Step 3 — Import into LoopGantt

  1. Save the converted output as my-project.json.
  2. In LoopGantt, click Import → Import from JSON.
  3. Select your file and click Import.
Large projects: MS Project files can have hundreds of tasks. If the AI times out or truncates the output, split your project into phases and convert one phase at a time, then merge the JSON arrays manually.

What doesn't transfer

Some MS Project features have no equivalent in LoopGantt:

  • Resource assignments (LoopGantt doesn't have resource management yet)
  • Cost tracking and budgets
  • Multiple calendars per task
  • Recurring tasks
