Hi, I'm Subham Ghadge
Data Analyst, Excel Developer & Office Automation Specialist · Maharashtra, India
I work with data and spreadsheets every single day. Over time, I kept noticing the exact same operational bottlenecks across offices everywhere: vendors billing for billable hours that never occurred, payroll calculations taking three managers three full days to reconcile, utility invoices nobody could properly audit, and employee attendance trapped in manual registers.
To solve this, I started engineering targeted spreadsheet tools. Not bloated or overpriced software, but robust, clean, and formula-driven Excel models built to solve practical operational headaches on day one.
That is the core mission of Subu Data Labs. It is an open technical library of field-tested Excel systems, dynamic Power BI dashboards, and custom VBA automation scripts. Every single template on this platform originated from an actual operational problem I either solved personally or built for an active business.
What We Specialize In
- Automated Operational Systems: Attendance registers, vendor payroll calculation sheets, and multi-tier billing dashboards.
- Advanced Excel Architecture: Dynamic formula modeling using
XLOOKUP,INDEX/MATCH,SUMIFS, dynamic arrays, and automated Pivot Tables. - VBA Macro Automation: Error-free macros that convert multi-hour repetitive manual data entry into single-click workflows.
- Interactive BI Reporting: Modern Power BI and Excel executive dashboards designed to deliver clear commercial insights.
- Open Technical Knowledge: Open-access educational workbooks with unlocked formula architectures and comprehensive structural breakdowns.
Real-World Implementation Experience
I have engineered custom operational spreadsheets for coworking spaces managing over 15 corporate tenants, real estate portfolios auditing rental yields across multiple properties, automotive dealerships monitoring inventory turnover, and facility management teams catching billing discrepancies in monthly utility invoices.
Most small-to-midsize operations do not need expensive enterprise ERP software to operate efficiently. A laptop with a properly structured Excel workbook is often faster, more flexible, and highly cost-efficient and agile when engineered with sound data principles.
Our Open-Access Promise
All analytical frameworks and companion workbooks published on Subu Data Labs are open-access educational resources for operational research and self-study. No forced registrations, paywalls, or trial restrictions. If a framework helps streamline your operational workflow, this project has succeeded.
Custom Consulting & Projects
If your organization needs a custom automated model built specifically around your internal operational data, whether that involves custom VBA scripts, multi-source KPI dashboards, or automated reporting systems, I take on select freelance development projects.
