Engineering Standard & Company Mission

Why We Build Native Excel Systems Instead of Another $99/mo SaaS

Datasheetly is an independent spreadsheet engineering studio. We build robust, macro-free Microsoft Excel (.xlsx) workbooks for small businesses, contractors, and finance teams who want deterministic operational control without recurring subscription taxes.

Zero Macros (100% VBA-Free)

VBA macros trigger IT security quarantines, antivirus blocks, and break on Excel for Mac and Excel on the Web. Every Datasheetly system uses pure modern Excel dynamic formulas. Zero security headaches.

FAST Modeling Standard

We adhere to the international FAST standard: Flexible, Appropriate, Structured, and Transparent. Inputs (Blue) are strictly decoupled from Calculation Engines (Black) and Executive Presentation Sheets (Green).

Perpetual DRM-Free Ownership

Pay once ($9 single / $24–$35 packs). Download native .xlsx files. Keep them forever on your hard drive, local server, or SharePoint. You never lose access to your data or suffer forced cloud migrations.

The Datasheetly Quality Criteria

How Every Datasheetly Workbook is Engineered

Before any workbook enters our live catalog of 103 systems, it must pass a strict 6-point technical QA standard:

1. Zero VBA / 100% Macro-Free:Pure OpenXML (.xlsx) files. Never quarantined by corporate antivirus software or restricted IT firewalls.
2. Formula Separation of Concerns:No raw data is mixed into KPI rollups. Raw entry feeds structured tables, which feed calculations, which feed summary charts.
3. Modern Dynamic Array Engine:Built with LET, XLOOKUP, FILTER, and SUMIFS for instantaneous calculation across 2,000+ to 10,000+ data rows.
4. Dual Production Files Included:Every Pro purchase includes both a fully pre-filled working example (to see the model in action) and an unpopulated blank production file.
5. Print & PDF-Ready Layouts:Executive dashboards and invoices are formatted with pre-configured A4/Letter margins, page breaks, and clean print areas.
6. Zero Circular References & Strict Validation:Every sheet undergoes automated error audits (#REF!, #DIV/0!, #NAME?) with cell protection locks to prevent broken formulas.
