Rendlio documentation

Rendlio converts .xlsx / .xlsm workbooks to PDF, PDF/A-2b, or PNG on your own machines — no Office, no LibreOffice, no network. Every conversion emits a machine-readable compatibility report that names every deviation from faithful rendering, so nothing is ever silently approximated.

Five minutes gets you a first PDF and its report.

Quickstart

Install The .NET global tool, the container image, the four archives — and how to verify a release.

CLI reference Every command, flag, and environment variable, with types and defaults.

Compatibility report The report v1 schema, status semantics, warning codes, and CI gating with jq.

Licensing guide The BUSL source licence, the tier table, and how the offline licence file works.

Deployment Docker, GitHub Actions, GitLab CI, air-gapped hosts, and the resource-limit registry.

Fidelity methodology How every fidelity number is produced: the oracle, the rubric, and the provenance.

Security model Every workbook treated as hostile — parser guards, resource caps, no network egress.

FAQ What Rendlio converts, whether it needs Excel, how per-entity licensing works, refunds.
