docxtractr

Extract Data Tables and Comments from ‘Microsoft’ ‘Word’ Documents

Description

An R package for extracting tables & comments out of Word documents (docx). Development versions are available here and production versions are on CRAN.

Microsoft Word docx files provide an XML structure that is fairly straightforward to navigate, especially when it applies to Word tables. The docxtractr package provides tools to determine table count, table structure and extract tables from Microsoft Word docx documents.

Many tables in Word documents are in twisted formats where there may be labels or other oddities mixed in that make it difficult to work with the underlying data. docxtractr provides a function—assign_colnames—that makes it easy to identify a particular row in a scraped (or any, really) data.frame as the one containing column names and have it become the column names, removing it and (optionally) all of the rows before it (since that’s usually what needs to be done).

What’s in the tin?

The following functions are implemented:

  • read_docx: Read in a Word document for table extraction
  • docx_describe_tbls: Returns a description of all the tables in the Word document
  • docx_describe_cmnts: Returns a description of all the comments in the Word document
  • docx_extract_tbl: Extract a table from a Word document
  • docx_extract_all_cmnts: Extract comments from a Word document
  • docx_extract_all_tbls: Extract all tables from a Word document (docx_extract_all is now deprecated)
  • docx_tbl_count: Get number of tables in a Word document
  • docx_cmnt_count: Get number of comments in a Word document
  • assign_colnames: Make a specific row the column names for the specified data.frame
  • mcga : Make column names great again
  • set_libreoffice_path: Point to Local soffice.exe File

The following data file are included:

  • system.file("examples/data.docx", package="docxtractr"): Word docx with 1 table
  • system.file("examples/data3.docx", package="docxtractr"): Word docx with 3 tables
  • system.file("examples/none.docx", package="docxtractr"): Word docx with 0 tables
  • system.file("examples/complex.docx", package="docxtractr"): Word docx with non-uniform tables
  • system.file("examples/comments.docx", package="docxtractr"): Word docx with comments
  • system.file("examples/realworld.docx", package="docxtractr"): A “real world” Word docx file with tables of all shapes and sizes
  • system.file("examples/trackchanges.docx", package="docxtractr"): Word docx with track changes in a table
