Text hygiene by taxonomy field
Source: IUCN Red List 2026-1 (CSV export, taxonomy file) · 8 rows
The table below profiles the text of each taxonomy field, one row per field and characteristic: what share of the field's values have surrounding whitespace, repeated spaces, non-breaking or control characters, or non-NFC Unicode normalisation. Counts cover every value in the field.
Why it matters
This profile shows which fields have the most text irregularities, so cleanup effort can be aimed where it has the most effect.
Suggestion
Use the percentages to prioritise. Fields with a high share of surrounding whitespace, repeated spaces, or non-NFC values are the best candidates for a normalisation pass.
