Structured XBRL segments plus an external denominator

Compare growth against the industry

Which of Walmart's segments grew fastest, and did the company beat its industry?

Two calls that answer different halves of one question. The first reads the segment tables out of the filing's own XBRL, by business segment, product line and geography. The second puts the company's revenue growth next to the Census retail total for its industry, so "grew 4.7%" becomes "grew 2.6 points faster than general merchandise retail".

Recorded Walmart Inc., 10-K filed 2026-03-13, fiscal year to 2026-01-31, on 23 October 2026 against parser version 3. Responses are trimmed to the fields the example is about; elisions are marked.

What to take from this

• The sector series is chosen from the filer's SIC code, and the choice is reported as chosen_by along with the series id and a link, so you can disagree with it. Pass sector to override it.
• Growth is a fraction in both tools, as it is everywhere in this API. 0.047255 is 4.73%.
• This is the one filings tool that reads something other than EDGAR. The series is Census retail trade, read through the FRED mirror of the same series when no Census key is configured, and meta says which path answered.
