How do you write a fast browser script to convert a local JSON file into a valid CSV table layout?

Question

I have a database backup stored as a nested javascript JSON array object. What is the basic frontend logic loop to parse these records into a clean download link?

DevExpert · Answer

Extract the object keys to form the primary column header string array. Loop through each row object, extract values separated by semicolons using .join(';'), combine text, and export via Blob URL.
