About
Independent reference site
This project reorganizes official classification files into browseable static pages so lookup, hierarchy checks, and crosswalk inspection are faster than working inside spreadsheets alone.
Scope
SSIC 2025, SSOC 2024, ISIC Rev. 5, and crosswalk pages.
Source policy
Official SingStat and UN Stats files remain the authority.
What the site does
It turns spreadsheet structures into stable URLs, keeps parent-child navigation visible, and gives crosswalk rows a real destination page. That makes classification work easier to inspect on mobile and desktop.
Each code page includes hierarchy context, crosswalk mappings, related entries, and links to official source files. The goal is to reduce the time spent switching between SingStat workbooks.
What the site does not do
It does not replace official guidance, legal interpretation, or filing instructions. If a row in this site conflicts with a source workbook, the source workbook wins.
It does not provide real-time data, user accounts, or interactive tools. All content is static and generated from official spreadsheets at build time.
