Date format in JSON: parsing and pipeline guide
Blog post from CodeWords
JSON lacks a native date type, which often leads to challenges in handling dates across different systems, as dates are typically represented as strings or numbers. This absence of a standard date format has led to ongoing issues and debates, as highlighted in the 2024 Stack Overflow Developer Survey, where date/time handling is cited as a major frustration. Although JSON has no official date format, ISO 8601 has become the practical standard due to its widespread adoption by major technology companies and API design guidelines. Unix timestamps offer a clear alternative by avoiding parsing ambiguity, but they sacrifice human readability. The text discusses how different programming languages handle JSON date parsing and emphasizes the importance of normalizing dates in data pipelines, particularly when dealing with multiple API integrations. It highlights the necessity of handling timezones and validating dates to prevent errors in processing. The CodeWords platform is showcased as a solution for normalizing and validating dates during data processing, ensuring consistency and reliability across systems by converting all dates to a standard format before further processing.
