# PDF Table Extractor to CSV/JSON Extract tables from PDFs with OpenDataLoader and export them as structured JSON, flat CSV, or HTML tables > Canonical page: https://elysiatools.com/en/tools/pdf-table-extractor-to-csv-json - **Category:** Data Processing - **Keywords:** pdf, table, csv, json, extractor ## Overview Use OpenDataLoader table extraction to identify semantic table blocks in a PDF and export them as JSON, CSV, or HTML. This is useful for reports, statements, research PDFs, and data-heavy documents that need table reuse. ## Inputs - **PDF File** (file) - **Export Format** (select) - **Table Detection Method** (select) - **Pages** (text): e.g. 1,3,5-7 - **Use Struct Tree** (checkbox) ## When to use - Extracting financial data from annual reports into spreadsheets for analysis. - Converting research paper data tables into machine-readable JSON for database ingestion. - Pulling tabular line items from digital invoices or statements into flat CSV files. ## How it works - Upload your PDF file containing the tables you want to extract. - Select your preferred export format (JSON, CSV, or HTML) and specify page ranges if needed. - Choose the table detection method (Default or Cluster) and optionally enable the PDF structure tree. - Download the extracted tables in your chosen format for immediate use. ## Use cases - Financial analysts extracting balance sheets and income statements from corporate PDF reports into CSV for Excel modeling. - Data scientists converting statistical tables from academic PDFs into structured JSON for programmatic analysis. - Operations teams pulling tabular line items from digital purchase orders into HTML for web-based previews. ## Frequently asked questions ### What export formats are supported? You can export extracted tables as structured JSON, flat CSV, or HTML tables. ### Can I extract tables from specific pages only? Yes, you can specify a page range (e.g., 1,3,5-7) to limit extraction to specific parts of the document. ### What is the difference between JSON and CSV output? JSON retains metadata like page numbers, bounding boxes, and grid structure. CSV flattens the data into a simple table, page, row, column, and value format. ### What does the Use Struct Tree option do? It leverages the internal structural tags of the PDF (if available) to improve the accuracy of table boundary detection. ### What are the table detection methods? You can choose between Default and Cluster methods. The Cluster method groups text elements based on spatial proximity to identify table grids. ## Related tools - [Fitness Workout PDF Generator](https://elysiatools.com/en/tools/fitness-workout-pdf-generator): Generate a printable workout-plan PDF from JSON or CSV data with exercise tables, progress boxes, and optional QR video links - [PDF Invoice Generator](https://elysiatools.com/en/tools/pdf-invoice-generator): Generate a branded invoice PDF from structured line items - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [CSV / Excel Diff Tool](https://elysiatools.com/en/tools/csv-excel-diff-tool): Compare two CSV or XLSX datasets and export a PDF report with row, column, and cell-level differences - [PDF Annotation Export](https://elysiatools.com/en/tools/pdf-annotation-export): Extract existing annotations (highlights, comments, stamps, links, markup) from a PDF into JSON - [PDF Form Data Export](https://elysiatools.com/en/tools/pdf-form-data-export): Read AcroForm field names, types and current values from a PDF and export them to JSON - [PDF to JSON Structure Explorer](https://elysiatools.com/en/tools/pdf-to-json-structure-explorer): Extract structured OpenDataLoader JSON from a PDF and browse headings, paragraphs, tables, lists, pages, and bounding boxes in an explorer view - [CSV Transformer](https://elysiatools.com/en/tools/csv-transformer): Transform and process CSV data with column operations, calculations, and data type conversions.
