Automate Compliance Checks with Certificate Of Analysis OCR
Use LlamaParse to extract COA tables and specs accurately, then flag issues with confidence scores.
Parse Certificates of Analysis into Structured JSON
LlamaParse turns messy Certificates of Analysis into clean, consistent JSON, capturing test results, units, limits, and identifiers across shifting layouts. Agentic document parsing applies layout-aware vision, validation loops, and verifiable citations so your QA and compliance pipelines stop breaking.
Best-in-Class Accuracy
Unlock Structured Data from Every Certificate of Analysis
Pharmaceutical Manufacturing & Quality Control
Parse supplier Certificates of Analysis into structured JSON, preserving complex test-method tables, limits, and units so QC can auto-validate incoming lots against specs. LlamaParse adds page-level citations and confidence scores to every extracted result, making deviations auditable without manual re-keying.
Food and Beverage Production & Supplier Compliance
Convert COAs for allergens, microbiology, and nutrition into clean, layout-faithful outputs that keep multi-column tables and batch identifiers intact. Use natural-language parsing instructions to standardize disparate supplier formats into a single schema for faster release decisions and fewer hold-ups at receiving.
Industrial Chemicals Distribution & Procurement
Automatically extract purity, assay, trace metals, and lot details from inconsistent COA layouts, including scanned PDFs with stamps and embedded charts. Cost Optimizer and tier-based processing route only the messy pages to heavier models, helping teams scale COA intake without runaway per-document spend.
Startups Building Laboratory and Supply Chain Software
Ship COA ingestion in days by using LlamaParse as the document processing layer—turn any supplier PDF into Markdown/JSON that drops directly into your product database and workflows. Granular metadata and traceable citations let you build customer-facing verification and exception review without writing brittle parsing code.
The Solution
OCR Features Built for Certificate of Analysis (COA) Data Extraction
01
Layout-Aware COA Table Capture
LlamParse understands page layout and preserves reading order, so COA sections like “Test / Method / Specification / Result” don’t get scrambled into unusable text. It reliably extracts dense tables, multi-column blocks, and footnotes so you can trust every value during QA review.
02
Structured JSON Extraction Mode
Export COA content as clean JSON so fields like lot number, product name, test dates, and per-analyte results land in your LIMS/ERP without brittle post-processing. Each extracted element can include page and position metadata, making audits and downstream validation straightforward.
03
Validation and Auto-Correction Loops
LlamaParse applies iterative validation to catch common scan and parsing failures like swapped units, missing decimals, and misread characters in batch IDs. That reduces manual re-checks and increases straight-through processing when ingesting large volumes of supplier COAs.
04
Multimodal Figure and Stamp Parsing
COAs often include signatures, stamps, small charts, and embedded images; LlamaParse can interpret these visual elements instead of ignoring them as “non-text.” You get a more complete record, including key annotations and visual qualifiers that matter for compliance decisions.

Common FAQs
How Does it Work?
01
Will the OCR keep COA tables in the right order (Test / Method / Specification / Result) instead of scrambling columns?
01
Will the OCR keep COA tables in the right order (Test / Method / Specification / Result) instead of scrambling columns?
Yes—layout-aware capture preserves reading order across dense tables, multi-column sections, and footnotes so values stay aligned with the correct test and spec. This reduces QA rework and prevents mismatched results that can lead to incorrect release decisions.
02
Can I export COA data as structured JSON for my LIMS or ERP?
02
Can I export COA data as structured JSON for my LIMS or ERP?
You can export clean JSON with key fields like lot/batch number, product name, dates, and per-analyte results—ready for mapping into your systems. Optional page and position metadata makes it easy to validate extractions and support audits.
03
How does it handle common scan errors like missing decimals, swapped units, or misread batch IDs?
03
How does it handle common scan errors like missing decimals, swapped units, or misread batch IDs?
Validation and auto-correction loops flag and fix common OCR failures such as decimal shifts, unit confusion, and look-alike characters (e.g., O/0, I/1). The result is higher straight-through processing and fewer manual spot checks.
04
Do you capture signatures, stamps, and other non-text elements on COAs?
04
Do you capture signatures, stamps, and other non-text elements on COAs?
Yes—multimodal parsing can interpret and extract key visual elements like signatures, stamps, small charts, and embedded images rather than dropping them. That gives you a more complete compliance record for review and retention.
05
What if my COAs have inconsistent supplier formats and messy layouts?
05
What if my COAs have inconsistent supplier formats and messy layouts?
The parser is built for real-world variability, handling different templates, rotated pages, mixed font sizes, and cramped tables without requiring custom rules for every vendor. You get consistent outputs that are easier to standardize across your supplier base.
06
How can I verify extracted values during QA or an audit?
06
How can I verify extracted values during QA or an audit?
Each extracted element can include page and location references so reviewers can quickly trace a JSON field back to the exact spot on the document. This speeds up investigations, supports audit readiness, and increases confidence in automated ingestion.
