Format conversion looks trivial until it silently mangles your data. These posts are about the places it does.<\/p>\r\n
What you will find: why Base64 makes a file roughly a third bigger and why we still use it; what UTF-8 actually does to a character above the ASCII range, and why \"just encode it\" corrupts a name with an accent in it; the difference between encoding a whole URL and encoding one query parameter, and why getting that backwards breaks the link; why a JSON number is not the same thing as a database integer once it passes 2^53.<\/p>\r\n
There is a deeper piece on JSONPath \u2014 the query syntax, not the button \u2014 because once you understand the grammar you stop guessing at expressions and start writing them.<\/p>\r\n
Aimed at backend developers, data analysts and QA engineers who move payloads between systems all day and would rather find the encoding bug now than in production.<\/p>\r\n
