This file contains header information and word counts for all 10X filings. 

  • The header data is pipe-delimited from the word counts.
  • The word counts appear as word-sequence-number:word-count.
  • A Python function to decode the records is here.
  • A sample program to produce word counts using the function is here.


Here is a truncated line containing Google's first 10-Q filing:

The first six fields before the pipe are: (1) cik, (2) filing_date, (3) accession_number, (4) conformed_period_report, (5) form_type, and (6) company_name.

The subsequent fields contain the word sequence number in the master dictionary followed by the count for that word. The first field (101:42), indicates that the word "ability "occurred 42 times in the filing.
