Show HN: Parsr – A toolchain to transform documents in usable structured text

Turn your documents into data!

Français | 中文

Parsr, is a minimal-footprint document (image, pdf) cleaning, parsing and extraction toolchain which generates readily available, organized and usable data for data scientists and developers.

It provides users with clean structured and label-enriched information set for ready-to-use applications ranging from data entry and document analysis automation, archival, and many others.

Currently, Parsr can perform:

• Document Hierarchy Regeneration - Words, Lines and Paragraphs
• Headings Detection
• Table Detection and Reconstruction
• Lists Detection
• Text Order Detection
• Named Entity Recognition (Dates, Percentages, etc)
• Key-Value Pair Detection (for the extraction of specific form-based entries)
• Page Number Detection
• Header-Footer Detection
• Link Detection
• Whitespace Removal

Parsr takes as input an image (.JPG, .PNG, .TIFF, ...) or a PDF generates the following output formats:

• JSON
• Markdown
• Text
• CSV (for tables), or Pandas Dataframes (see here )
• PDF
