Frequently Asked Questions
Does this template require enabling macros or VBA code?
No. All Datasheetly templates are 100% macro-free (.xlsx). They rely on native modern Excel formulas (XLOOKUP, SUMIFS, LET), never trigger antivirus blocks, and are completely safe for corporate computers.
Are there any recurring subscriptions or extra fees?
None whatsoever. You make a single one-time payment of $9 and own the DRM-free Excel workbook files forever. No monthly recurring charges, no per-seat fees, and no cloud lock-in.
What software versions are required to run this workbook?
Datasheetly workbooks are engineered for modern Microsoft Excel: Microsoft 365 (Windows & Mac), Microsoft Excel 2021+, and Excel for Web (free online via office.com with any Microsoft account). Because our models leverage modern dynamic array formulas (LET, XLOOKUP, FILTER, SUMIFS) and native Excel structured tables, they are designed exclusively for Excel. Older legacy releases (Excel 2019/2016) and third-party spreadsheet viewers do not support these modern formula engines.
Do I receive clean blank files for my company data?
Yes! In your download vault, you receive two separate workbooks: a Sample Data Workbook (with realistic pre-filled rows to inspect formulas) and a Clean Blank Workbook (with all formulas and formats ready for your live data).
What if the template doesn't meet my business needs?
Every purchase is backed by our 30-Day Defect & Satisfaction Guarantee. If any formula fails or the template does not perform as documented, simply contact support for an immediate resolution or refund.
