Free document tool
Free tool to extract PDF text, tables, and metadata into JSON
Convert a PDF into named fields and rows, then map the JSON on your terms.
Upload a native or scanned PDF and extract its named fields and repeating rows. Review the values beside the source, download JSON, then map that result into the versioned contract your application expects. Parseable does not mean correct, so keep validation at the boundary.
Content reviewed .
JSON, CSV and Excel downloads are included on Free after signup, within Free plan limits. See Free limits.
Anonymous originals stay in browser storage, not cloud file storage. Extraction may send document content to the selected AI provider.
Upload a PDF. PDF files are supported up to 50 MB.

What is included in the PDF JSON export?
Dynamite Docs extracts fields and tables from a PDF, keeps the values available for source review, and exports JSON with column definitions, rows, and document metadata.
The download is a product export, not your application schema. Validate required fields, identifiers, dates, decimal precision, arrays, and null handling before using it in code.
How do you convert unstructured PDF content into structured JSON data?
Use PDF to JSON when a report, operational log, or mixed-content PDF needs to be transformed into structured JSON objects with document metadata and table row arrays. Start by establishing your application schema requirements: required properties, expected array shapes, and explicit null-handling rules.
During review, cross-check named header fields and table boundaries against the original pages. Ensure that numbers, dates, and identifiers preserve their correct data types, that wrapped descriptions do not fragment rows, and that optional fields are normalized consistently across extractions.
Choose the PDF Table Extractor when table recovery is the sole objective without nested metadata. Use Invoice to JSON for commercial supplier invoices with tax, vendor, and line-item hierarchies. Use PDF to CSV for flat database table imports. For automated software delivery, integrate directly with our REST API using saved extraction schemas.

Dynamite Docs keeps the source and structured result in one review workspace. Infer document fields and repeating rows, correct values against the page, inspect warnings and export the accepted result.
This is more than a plain OCR transcript. The result separates fields, line items, totals and notes so a person can check the structure before sending data to Excel, CSV, JSON, Google Sheets, Google Drive, a webhook or the API.

Choose a hosted model or connect your own provider key for the extraction.
Provider keys are encrypted before storage. Compare processing options or follow the setup guide.
What the structured PDF JSON contains
- Named values found outside tables can be reviewed as document fields before they are mapped into an object.
- Detected tables retain column definitions and row arrays so repeating records do not collapse into plain PDF text.
- The export includes product metadata and reviewed values; downstream code decides the final nesting, property names, and required fields.
- Document identity and table records remain separate, which helps a mapper avoid repeating a report period, account or title inside every row. Several detected tables can be handled as separate datasets.
- Identifiers, dates and decimal amounts need explicit typing rules. Preserve the reviewed source representation so an application can explain how it normalized a date, retained a leading zero or rounded a value.
- The result is suitable for inspection and mapping, not direct trust. A production consumer should validate required properties, allowed values, array shape and cross-field rules before accepting the payload.
Document fields and tables for JSON export
The JSON download contains columns, rows and document metadata. The fields below illustrate what to check, not a fixed output schema.
- document_type: monthly_report
- title: Operations summary
- period: August 2026
- fields: Named values found on the page
- rows[]: Records from the selected result table
- dates: Normalized date values
- amounts: Numbers without display formatting
- source context: Compared in the review workspace
Extract first, then decide what to keep
- Upload and extract one PDF without creating an account.
- Review low-confidence values beside the source document.
- JSON, CSV and Excel downloads are included on Free after signup, within Free plan limits.
- Starter and above add stored files, batch jobs and connected exports. Email intake requires Pro or Scale. File and processing limits depend on your plan.
Compare batch-processing plans or read how extraction and review work.
Define what downstream code expects
Inspect nested objects, arrays, data types, missing values, and field names. For repeatable automation, save a reviewed schema instead of relying on fresh inference each time.
Cases that need manual review
- Reading-order text from a multi-column PDF can attach a label to the wrong value when visual structure is ambiguous.
- Several unrelated tables need separate mappings instead of one combined rows array.
- Application code can silently coerce dates, large identifiers, and decimal amounts unless it validates the reviewed JSON types.
- A valid JSON document can still omit a page, duplicate a repeated header or assign the wrong label to a value.
- Optional fields can vary between null, empty text and absence unless the mapping contract defines one representation.
- Schema inference may produce different column names for similar layouts. Passing those names directly to consumers creates a fragile integration.
- Prototype structured data from a new PDF type
- Prepare a JSON sample for an integration
- Extract fields and tables in one pass
- Test a versioned mapping before production delivery

Is PDF to JSON the same as extracting PDF text?
No. Plain text extraction follows reading order. This tool tries to identify named fields, data types, tables, and repeating records that software can use.
Can it return nested JSON?
The download contains column definitions, a rows array and document metadata. Map those values into nested objects if your application needs a different structure.
How do I keep the same schema across many PDFs?
Use a preset or saved schema in the workspace, then validate each result before it reaches downstream code.
Should my application consume the inferred JSON directly?
Use a mapping and validation layer. Translate reviewed columns and metadata into your own versioned contract, reject missing or unexpected fields, and send failures to an exception queue. This protects consumers when layouts or inferred field names change.
How should JSON represent numbers, dates and identifiers?
Treat money with decimal-safe rules, preserve currency separately and normalize dates only after confirming the source format. Keep account numbers, reference codes and other identifiers as strings so leading zeroes and punctuation are not lost.
