Does Bildstak connect to Excel and Google Sheets?

Yes, Bildstak connects to Excel workbooks and Google Sheets as native data sources. Many project teams keep critical data in spreadsheets — cost trackers, risk registers, procurement logs, milestone schedules, benchmark unit rates — and Bildstak reads those directly without requiring migration.

How the integration works:

• Live reads — Bildstak queries the spreadsheet at the time of the request. For Google Sheets, it uses the Google Sheets API to read the current data; for Excel, it reads files from connected cloud storage or uploads.
• AI queries — once connected, you can ask questions across the spreadsheet data in plain English: "what is the current forecast at completion on the mechanical package from the cost tracker?" gets an answer cited to the relevant cell range.
• Cross-source joins — if your spreadsheet uses the same element reference, WBS code or activity ID as another source (IFC, P6, SAP), Bildstak can join across them. Add a GlobalID column and spreadsheet data is linked directly to IFC elements.
• Reports and dashboards — spreadsheet data feeds into Bildstak's report builder and scheduled reports alongside every other connected source.
• Benchmark data — historical unit rates held in Excel from past projects are a common source for Bildstak's estimation and benchmarking module.

For teams not yet on a formal cost or project management platform, Excel or Sheets connectivity means you can still get AI-powered analysis of your project data immediately.
