Working with html table to csv

JSON represents structured values and nested objects. CSV and TSV represent rows and columns, making them convenient for spreadsheets and bulk imports. Moving between these formats changes what can be represented directly: a nested object needs a defined mapping to a flat table.

Common questions

Can JSON and CSV make a lossless round trip?

Not in every case. CSV does not carry JSON data types or nested structure. Decide how numbers, nulls, missing values and nested arrays should be represented rather than assuming a reverse conversion restores them.

Why does a comma create an extra column?

A separator inside a cell must be quoted using the rules of the file format. Newlines and quotation marks inside cells also need proper escaping. Changing the delimiter can help, but it does not repair malformed quoting.
