Converting Identifiers Between Cases
Crossing a boundary — API to database, one language to another — often means changing case. Here is how to do it cleanly.
API and database boundaries
A JSON API may use camelCase while the database uses snake_case. Converting field names at the boundary keeps each side idiomatic without renaming everything.
Batch with care
When converting many identifiers, watch for acronyms and numbers, which can split unexpectedly. Review the output rather than trusting a blind transform.
Frequently asked questions
Can I use this for production work?
Yes, for inspection, formatting and quick generation. Still review the output before committing it to production code or configuration.
