Yvonne Butler

Yvonne Butler focuses on the diagnostic side of JSON, writing about parsing failures, validation errors, and the practical work of figuring out why a payload won't load. Her approach is methodical, she'll take a broken snippet, isolate the issue, and explain the fix in a way that makes the underlying rule clear. She often structures articles around a specific error message and works backward from there.

She digs into recurring problems like unescaped strings, Unicode handling across different encodings, and the subtle differences between JSON-spec compliance and what browsers or APIs actually accept. Yvonne also writes about number precision, large integer behavior, and how trailing whitespace can cause issues in strict parsers. Edge cases involving deeply nested structures or unusually large files get particular attention because they reveal where formatting assumptions break down.

She draws a firm line between explaining how JSON parsing works and advising anyone on how to handle data in their own systems. Her articles describe behavior and document what's known, but they don't substitute for a thorough review of an application's requirements. Readers dealing with sensitive or regulated data are encouraged to consult their own technical leads before applying anything suggested here.
