TaguaReports 

A .NET reporting engine: YAML or JSON templates plus your data make accessible, archival PDFs. Tagged for screen readers, PDF/A and PDF/UA compliant, and ready for Factur-X e-invoices. Native AOT compatible.

The tagua command: render Tagua templates to PDF, preview them as you edit (render --watch), convert RDLC reports to templates, and print the template JSON Schema.

OpenType text shaping for Tagua reports with HarfBuzz: Arabic, Hebrew, Indic and other complex scripts.

Converts SSRS and ReportViewer report definitions (RDLC and RDL, 2005 to 2016) to Tagua templates, and lists anything that needs review.

Excel output for Tagua reports: a workbook built from the report's data, with numbers and dates as such, Excel formats from the template's, collapsible groups and a frozen header. No other dependencies.
