CSV Output

Export JSON rows to CSV

Analytics teams and spreadsheet users think in columns, not nested trees. CalcForge walks JSON arrays (or flattens objects) and writes comma-separated rows with a header line—ready to download or paste into your favorite sheet tool.

Good fits

Sharing API query results with non-developers
Building ad hoc reports from JSON log extracts
Preparing bulk mail-merge or CRM import files
Quick sanity checks on array length and column coverage

JSON:
[{"sku":"A1","qty":3},{"sku":"B2","qty":1}]

CSV:
sku,qty
A1,3
B2,1

Practical notes

Deeply nested objects may need JSON Flatten first for clean columns.
Arrays inside cells often stringify—flatten or pick fields before export.
UTF-8 encoding preserves international characters in modern spreadsheet apps.

Frequently asked questions

Can I convert a single JSON object?

Yes—often as one row or wrapped in an array. Nested keys may become dot-path column names depending on options.

How are null and boolean values exported?

They typically appear as empty cells or literal true/false strings. Open in your target app to confirm import behavior.

What delimiter is used?

Standard comma separation with RFC-style quoting when fields contain commas or quotes.
