Convert NACE Rev. 2 codes to Rev. 2.1

Paste a list of NACE or UK SIC codes, one per line or separated by commas, and get the matching codes in the other revision, the ISIC Rev. 4 code and a flag where one old class is split across several new ones. Runs in your browser.

Codes may be written with or without the dot (6201 or 62.01). A code that is not a four-digit class (for example 62 or J) is looked up as a division or section.
