Use the header as object keys and turn every following row into a flat JSON object whose cell values remain strings.
Inputs are limited to 1 MiB, 10,000 rows, and 256 columns.
Nothing is placed in a URL, account, or remote log.
Strict, bounded, local processing
String-valued output prevents accidental loss of leading zeros, large identifiers, or formatting that only looks numeric.
Each unique header becomes an object member name. Every data row must have exactly the same number of cells, including explicit empty cells between delimiters.
The converter preserves source order in the generated array and emits indented JSON for review.
A cell containing 0012 may be an identifier rather than the number twelve. Keeping cells as strings avoids a silent irreversible guess; convert fields with an explicit schema in the consuming application.
