About this free canonical source inspector tool
Extract canonical destinations and flag missing or multiple canonical declarations. Developer utilities inspect or transform data locally rather than contacting the address or service shown in your input. Use fictional samples while checking a format, keep credentials out of shared screenshots and validate the result against the receiving system. Successful parsing does not establish trust, security or schema correctness.
