Good to know.

What do I receive?

Every product includes editable blank CSV worksheets, populated example CSV files, a printable HTML workbook, a Markdown guide, license, notices and checksums. Connected kits include a cycle planner; products priced $39 and above also include a twelve-month review sheet. Product pages state the exact modules and file count.

How do I buy and download?

Add products to your cart or use Checkout on a product page. Review the order and policies, then continue to hosted secure payment. After payment is confirmed, check your checkout email for the payment receipt and a separate zzou download email. Links expire after 48 hours. The same browser can refresh downloads on the order page for up to 24 hours; contact zzou with your order reference for later access. If the payment provider is not configured, checkout explains that no payment can be taken and keeps your cart.

What software is needed?

Open CSV files in Excel, Numbers, LibreOffice or Google Sheets. Import using UTF-8 and comma separators if asked. Open printable.html in a modern browser, print landscape with fit-to-page, or save to PDF. Markdown opens in a text editor. No macros, formulas or paid app are required. These are file-based tools, not Notion workspaces or a hosted app.

Can I try a sample?

Each product page offers a worked example and downloadable CSV from its first module. Review formats before purchasing.
