Convert CSV to JSON Schema without losing useful fields
Column headings become schema properties. Consistent boolean and numeric samples are inferred; identifiers with leading zeros remain strings. Inference is a starting point, so review field types and required properties against the source system.
Check the output before importing it
The converter reports invalid or unsupported input rather than guessing silently. Review the generated values in the destination application, especially date formats, nested data and identifiers that may have special meaning there.
Example input
id,name,active 00123,Ada,true 00456,Linus,false
