JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy to read and write. It's commonly used for data exchange between web servers, web applications, and mobile apps.
Converting JSON data to VCF format is often necessary when working with genetic data stored in JSON format, such as data from the JSON-based format used by the Genome Analysis Toolkit (GATK) . There are several tools and libraries available for this conversion. json to vcf converter
# Create a VCF writer vcf_writer = vcf.Writer(open('output.vcf', 'w'), vcf.VCFHeader()) JSON (JavaScript Object Notation) is a lightweight data
