URL encoding explained (percent-encoding)
URL encoding (percent-encoding) in plain English: what to encode, how decode works, plus vs %20, and a safe no-upload workflow for debugging query strings.
Plus (+) vs space in query strings
A practical hub for Plus (+) vs space in query strings: what it means, common pitfalls (padding, UTF-8, URL-safe chars), and fast local fixes (no upload).
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
