// Deep Dive Converting JSON to CSV — Flattening, Types & Best Practices

JSON and CSV are shaped very differently, so a good converter has to make a few smart decisions along the way. Here's what's happening under the hood.

🧩

Why Flattening Matters

CSV is a flat, row-and-column format, but JSON supports nested objects and arrays. When a JSON record contains something like {"address":{"city":"NY","zip":"10001"}}, the converter flattens it into separate address.city and address.zip columns. This keeps every value accessible in the spreadsheet instead of collapsing it into an unreadable blob of text.

🏷️

Why Column Types Matter

Detecting whether a column is a number, boolean, or string helps you catch problems before they reach your spreadsheet — for example, a price field that's accidentally been stored as text, or an ID field mixed with letters and digits. The colour-coded badges in the preview table and Analysis tab make these inconsistencies easy to spot at a glance.

🎯

Getting a Clean Export

Before downloading, use the column toggles to drop fields you don't need — internal IDs, debug flags, or deeply nested metadata rarely belong in a final report. Sort the preview table by a key column to sanity-check the data, and if your source JSON came from a hand-edited file or a copy-paste, let the smart repair step run first so a single stray comma or bracket doesn't break the whole conversion.

// Reference Common JSON Structures & How They Convert

Quick guide to how different JSON shapes map onto CSV rows and columns.

JSON Structure	Example	How It Converts
Array of Objects Most Common	[{"id":1,"name":"Alice"}, …]	Each object becomes one CSV row, keys become column headers
Nested Object	{"address":{"city":"NY"}}	Flattened into dot-notation columns like address.city
Wrapped / Enveloped Array	{"data":[{...}], "meta":{...}}	The inner array is auto-detected and unwrapped for conversion
Single Object	{"id":1,"name":"Alice"}	Converted as a single-row CSV with one column per key
Scattered / Malformed JSON Auto-Repaired	Broken brackets, stray commas	Smart repair attempts to fix structure before conversion
