If the row only contains a string, it's stored in a "data" column, otherwise the row should usually be an object, so each of the object's variables will be used as a column name, and it's value analysed: - if it's a scalar, it'll be saved as a value of that column. - if it's another object, it'll be parsed recursively to analyzeRow(), with it's variable names prepended by current object's name - example: "parent": { "child" : "value1" } will result into a "parent\_child" column with a string type of "value1" - if it's an array, it'll be passed to analyze() to create a new table, linked by JSON\_parentId ### Health Score 37 — LowBetter than 81% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity20 Limited adoption so far Community19 Small or concentrated contributor base Maturity76 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
