style = one of block or inline.

Specifies whether structured objects in Maple should be to multi-line (block) or single-line (inline) output in JSON.

For example, if style=block a Maple list of three integers will produce a five-line JSON expression, while style=inline will produce a comma-delimited list on a single line.

The ToString(data) command formats the expression data as JSON (stored as a Maple string).

The input data must be a structured expression made only using the base types string, truefalse, realcons, and extended_numeric and the container types list, rtable, table, record, set(equation), DataSeries, and DataFrame.

$\mathrm{with}\left(\mathrm{JSON}\right)\:$

$\mathrm{ToString}\left(\left[\mathrm{table}\left(\left[''fruit''=''orange''\,''count''=23\right]\right)\right]\right)$

$''[\{"count":\; 23,\; "fruit":\; "orange"\}]''$

$\mathrm{ToString}\left(\left\{''a''=''b''\,''c''=6.283185308\right\}\right)$

$''\{"a":\; "b",\; "c":\; 6.283185308\}''$

The JSON[ToString] command was introduced in Maple 2015.

The JSON[ToString] command was updated in Maple 2020.
