Frequently Asked Questions

Is converting JSON to SQL (DDL / Inserts) secure and private?
Yes, 100%. All parsing, AST restructuring, and serialization occur directly inside your web browser using WebAssembly and lightweight pure-JavaScript runtimes. Your code and sensitive data are never transmitted to external servers or logged in any database.
How does DevFlow handle nested structures when converting JSON to SQL (DDL / Inserts)?
The conversion engine parses the input into an intermediate abstract syntax tree (AST). Nested hierarchies, primitive types (strings, numbers, booleans), arrays, and null values are mapped to their closest semantic equivalent in SQL (DDL / Inserts).
Can I automate this JSON to SQL (DDL / Inserts) conversion in CI/CD or terminal scripts?
Yes. You can install the official DevFlow CLI (`bun install -g @devflow/cli` or `npm i -g @devflow/cli`) and execute `devflow convert json sql -i file.json -o file.sql` in GitHub Actions, GitLab CI, or local git hooks.
What is the maximum file size supported for JSON conversions?
Because processing runs client-side, the converter comfortably handles files up to 25MB depending on your local browser memory limits, with zero network latency or upload timeouts.
