MPP File Viewer: Gantt Chart
Construction Schedule & XER
Free · In‑App Purchases
Compare revisions, save weekly minutes and map XLSX columns. Create small plans and export CSV or Project XML. One distinct file free.
Review received schedules before your next meeting. Open Microsoft Project or Primavera files, compare updates and keep decisions beside the plan.
REVIEW THE NEXT UPDATE
• Inspect Gantt charts, task dates and available resources. Share PDF reports and CSV tables.
• Group saved revisions and compare an update with your reviewed baseline.
• Save weekly minutes and carry open actions forward with owners and due dates. Reviewed minutes keep a fixed copy of what was discussed.
BRING IN A SPREADSHEET
Choose an XLSX sheet, heading row and task columns, then check every task row before opening. Selected formula and error cells are rejected; formulas are not calculated. CSV, TSV and tab-delimited TXT can also use column mapping.
CREATE A SMALL PLAN
Set task names, dates, progress and notes in an editable local draft. Valid drafts save automatically. Export CSV or Project XML with manual task dates. There is no MPP writing or dependency rescheduling.
ONE DISTINCT FILE FREE
Open one distinct file free and reopen that unchanged file. A changed revision counts as a new file. For more files, choose an annual or monthly subscription, a nonrenewing seven-day pass or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled; the seven-day pass does not renew. Prices and terms appear before purchase.
LOCAL PROCESSING AND YOUR CHOICES
Received originals stay read-only; created drafts are editable. File processing and meeting notes are local. Basic usage sharing is optional, off by default and changeable in settings. Usage counts contain no document text or recordings. No account is required.
