What is inside?

19 files in one ZIP.

Cases / Claims / Drafts / Reuse Excel sheets: blank and three-case fictional-demo XLSX
Four input CSV tables: blank and demo
Manual Notion setup and quickstart
Long case-study and short proposal Markdown templates
Three original fictional case narratives and test exercises

The Excel workbook provides 100 prepared rows per table. Extending capacity requires manual formula, range, validation and cross-reference updates across all four tables.

Each draft links one primary evidence record. Secondary claims and external assets require manual review; changes to external secondary evidence are not automatically detected. Workbook checks are editable, not protected or tamper-proof.

Keep the claim close to its context

Write what changed, save the supporting source, and record the relevant limitations. Review permissions and redactions before sharing client material. If a source does not support a claim, narrow the wording or leave the claim out.

Notion CSV files require manual import and property setup; Excel formulas, formatting, validation, relations, rollups and automated approval checks do not transfer. Follow the separate manual evidence, snapshot and permission-review workflow. Proof does not independently verify evidence, obtain permission or provide legal clearance. All included examples are fictional.

Review your spreadsheet changes

Open the free, open-source Sheet Check to compare two CSV or XLSX tables by a key column and inspect duplicate or missing keys. It processes files in your browser. Keep your original files: it does not recalculate formulas, validate product-specific business rules, or certify a workbook.

Questions before you download

Is there a subscription?

No. The Evidence Card is USD 0, with an optional contribution. The separate Client Case Study Studio is USD 12, paid once.

Is this a native one-click Notion template?

No. Import the CSV files and set up properties manually as instructed. Notion import does not recreate workbook formulas, formatting, validation, relations, rollups or automated approval checks. Evidence, snapshot and permission checks are manual.

Does Proof verify my evidence or clear it for publication?

No. Its checks help review the data you enter. You must verify claims, permissions and any limits on sharing client information. It does not provide legal clearance.

Are the examples real client results?

No. All sample cases are original fictional teaching examples, not customer results or endorsements.

Is individual support included?

Self-serve download. No setup, customization, or individual usage support included.

Compatibility and checks

Workbook formulas were checked in the authoring engine and independently recalculated in LibreOffice. Microsoft Excel desktop UI and live Notion import were not tested.
