Real-world examples
Shipping an API change
A backend engineer pastes a response payload into SQL Formatter to get it readable, then switches to CSV to JSON to confirm the change behaves the way the ticket describes. Two tabs, under a minute, nothing uploaded.
Cleaning up a client hand-off
A file arrives from a client in the wrong shape. CSV to JSON handles the conversion or check, and SQL Formatter produces the tidy version you actually send back. Because both run locally, client data never leaves the laptop.
Debugging in a hurry
Production is throwing an error and you have a blob of data and no context. SQL Formatter tells you what you are looking at; CSV to JSON tells you whether it is correct. Together they replace a much heavier desktop toolchain.
