How to Extract Tables From PDF
Tables in PDFs are notoriously difficult to extract because the PDF format doesn't store tabular structure — it positions individual text fragments on a page with no concept of rows, columns, or cells. Copy-pasting a PDF table into a spreadsheet produces a mangled mess of misaligned data. SublimePDF uses intelligent layout analysis to detect table boundaries, reconstruct row/column structure, and export clean tabular data to Excel, CSV, or other formats.

Open Tool →How to Extract Tables From PDF — Step by Step
Upload your PDF
Open the Extract Tables tool and upload the document containing the tables you need. The tool scans every page for tabular structures — grids of aligned text that form rows and columns.
Review detected tables
The tool highlights every detected table with a colored overlay, showing the identified rows and columns. Each table is numbered and you can see which page it was found on. Click any table to see its extracted data in a preview grid.
Adjust table boundaries
If the auto-detection merged two adjacent tables or missed a column boundary, manually adjust the detection box. Drag column separators and row separators to correct the structure. This is common with borderless tables.
Select tables to export
Check the tables you want to extract — grab specific ones or select all. If a table spans multiple pages, the tool attempts to merge continuation rows into a single table.
Choose output format
Export to CSV (universal spreadsheet format), Excel (.xlsx with formatting), JSON (for programmatic use), or HTML (for web publishing). Excel output preserves detected number formatting and column widths.
Download extracted data
Click 'Extract' to generate the output files. Each table downloads as a separate file (or tabs in a single Excel workbook). Open in your spreadsheet application and verify the data.
Pro Tips
- 💡 Tables with visible gridlines (borders around cells) are detected far more accurately than borderless tables. If you're creating PDFs for others to extract data from, always use visible borders.
- 💡 For multi-page tables, check that the header row is correctly identified. The tool needs to know which row contains column headers to properly merge data across page breaks.
- 💡 After extraction, spot-check numeric values — especially currency amounts and dates. OCR-like extraction can occasionally misread '0' as 'O' or '1' as 'l' in certain fonts.
- 💡 If extraction produces messy results on a borderless table, try adjusting the sensitivity setting. Higher sensitivity detects more subtle column alignment but may produce false column splits.

How to Extract Images From PDF
PDFs often contain high-resolution photos, charts, diagrams, or logos that you need as standalone image files for presentations, websites, or design work. Manually screenshotting pages loses quality and wastes time. SublimePDF extracts every embedded image from a PDF at its original resolution, saving each one as a separate JPG or PNG.
How to Extract Data From Invoices
Processing invoices manually — reading each PDF, finding the vendor name, invoice number, date, line items, and total, then entering it all into accounting software — is one of the most time-consuming accounts payable tasks. Invoice data extraction uses intelligent document analysis to automatically identify and pull structured data from invoice PDFs, regardless of layout differences between vendors. SublimePDF reads invoices and outputs clean, structured data ready for your accounting system.
How to Extract Attachments From PDF
PDFs can contain embedded file attachments — spreadsheets, source data, original images, supplementary documents, or even executable files hidden inside the document. These attachments aren't visible as pages but are bundled within the PDF file structure. Extracting them recovers the original files for editing, analysis, or archival. SublimePDF detects and extracts all embedded attachments from any PDF.
