Tool detail
Mekler: CSV validation
Validates a CSV against a fixed JSON column specification (types, required, uniqueness, allowed values, bounds) and returns pass/fail with row/column error codes.
Categories: Utilities
Use when
- validate a CSV's columns and cell types before import
- check a CSV for missing fields, duplicates, or out-of-range values
Not for
- not the spec-checking call — validating the column spec itself is a separate endpoint
- not fact-checking, cross-column rules, or data repair
Inputs
POST JSON body: { csv: string, spec: { columns: [...] } } (both required); max 2,000 rows, 50 columns, 256 KiB
Inputs undocumented: unsupported schema construct: oneOf
