DocKosha Cloud document processing

DocYantra powers DocKosha Cloud

A private, high-performance document processor for DocKosha Cloud’s supported Office and PDF workflows. Work outside its validated envelope fails closed.

Built for speed, fidelity, and fail-closed governance

DocYantra is the private processing engine inside DocKosha Cloud's validated Office and PDF path. It is not a standalone product or externally available package; work outside its documented envelope fails closed instead of degrading quietly.

Rust performance for managed processing

DocYantra provides a high-performance processing path for managed DocKosha Cloud workflows, with supported documents typically ready in seconds. DocKosha uses the mandatory direct DocYantra dependency.

  • The DocYantra validated path does not use a headless office suite or browser in the path
  • DocYantra uses isolated worker threads with finite deadlines and bounded queues
  • DocYantra validates output before it reaches the viewer

Multilingual, high-fidelity output

DocYantra can produce validated PDFs with compact glyph-subset fonts embedded, and resolve fonts on demand for math, symbol, and CJK coverage in supported Office documents.

  • DOCX, PPTX, XLSX, and XLSM conversion to PDF, plus CSV and Markdown rendering
  • Chinese, Japanese, and Korean text renders through pan-CJK Noto fonts
  • PDF merge, watermarking, and redaction through the DocYantra processing path

Fail-closed governance

DocYantra is built for controlled sharing where unvalidated output is not acceptable — anything outside the validated envelope fails closed with typed, stable error codes.

  • No silent quality loss and no tofu or placeholder glyphs
  • Converted assets are published only after output validation
  • The original remains available when preview conversion fails

Built for controlled sharing

  • Validated, deterministic DocYantra PDF output feeds DocKosha viewing, watermarking, redaction, and analytics.
  • DocYantra worker isolation keeps heavy document operations bounded by finite deadlines.
  • DocYantra’s compact glyph-subset fonts keep viewer PDFs lean without sacrificing fidelity.

Clear format boundaries

  • The DocYantra path converts modern DOCX, PPTX, XLSX, and XLSM files to PDF and renders CSV and Markdown.
  • Legacy .doc, .ppt, and .xls files and unsupported document features are rejected with typed errors.
  • CJK text in supported Office documents is supported; vertical text layout is not and fails closed.

How DocYantra works

01

Validate the file

DocKosha checks the format, size, and processing envelope before any document work begins.

02

Convert in an isolated worker

The DocYantra worker converts the document within a finite deadline; unsupported work returns a typed failure.

03

Publish validated output

Only a validated PDF becomes the viewer asset; failed conversions fail closed and leave the original available.
