Before parsing hundreds of PDFs, you parse a small sample with LlamaParse, compare the markdown with the originals for missing text, tables and headings, and only then scale up.

Goal
Find out whether parsing is good enough for your documents before you spend credits on all of them.

Steps
01
You
Choose 5 to 10 representative documents, including the hardest tables and scans
Compare each output with its original page by page and record what was missed
Human stepConfirmed
Confirmed means the vendor documents it (linked). It doesn't mean IonBin has tested it. AI-platform and human steps need no source.
Human approval
You decide whether to parse the full folder after checking the sample.
Watch out for
LlamaParse is a hosted service, so check your agreement and data retention before uploading confidential files. A higher tier costs more but doesn't guarantee every page is right, so measure on your sample.
Starter prompt
Here are the original page and LlamaParse's markdown output. List any missing sentences, table cells, headings or numbers, and any text that appears in the output but not on the page.

Readiness considers the connection evidence and unresolved steps. Confirmed: documented access and the proposed steps meet the recorded requirements. MCP and API pairings require an explicit reviewed platform note; a named plugin or CLI alone does not confirm MCP. Inferred: an explicit page note describes a plausible pairing that still needs testing. To verify: a connection or step is unresolved. An API and code execution alone do not establish compatible network access, credentials or permissions. None of this is IonBin testing.
What we checked (2026-10-18)
Parse API. LlamaParse needs a LlamaCloud API key, set as LLAMA_CLOUD_API_KEY, and can be used from Python, TypeScript, Java, the CLI, the REST API or the web UI.
Measure before scaling. The IonBin LlamaParse record notes that higher-cost settings are not evidence that every page is correct, and that hosted processing needs a check of the account agreement and retention first.
Set it up
Pick a sample that includes your hardest documents.
Parse the sample with the settings you plan to use at scale.
Compare outputs against the originals with the prompt above, and count missed tables and numbers.
Only parse the full folder if the sample meets your bar, and keep spot-checking afterwards.
Pilot it on a small sample first, and keep the human step even when the output looks right. This is a proposed sequence based on documented tools, not a tested account integration.
