Decide on headers before assigning field types
Convert table records between CSV and JSON. Check the delimiter and header option. Cells remain strings by default so identifiers and dates are not silently converted to numbers.
An example to check
Input and settings
name,count
Alice,2Expected result
[{"name":"Alice","count":"2"}]With the first row used as headers, the output is an array of records; count remains the string "2". For the reverse direction, check the record structure and column order.
Scope and limitations
- Cells containing delimiters or newlines need CSV quoting. Splitting blindly on commas can corrupt addresses and descriptions.
- Duplicate headers overwrite same-named fields. Inspect formula-like cells before opening a CSV in spreadsheet software, especially for untrusted data.
