Decode Base64 without uploading
Troubleshoot Decode Base64 without uploading with a safe workflow: detect the format, normalize it, and decode/encode locally (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.
