The USoft JSON format is a standardised way to represent USoft data in JSON. In this format, a top-level JSON object is allowed to contain data from a single table or from multiple tables.

This format is produced by calls to JSON.Export for data from a single table, and by calls to JSON.MultiExportTables for data from multiple tables. 

Data in this format is re-importable by calling JSON.Import.

Syntax

{
   json-table-section,  ...
}

json-table-section   ::=  "table-name" :   row-section, ... ]

row-section     ::=  { column-section, ... }

column-section  ::=  { "column-name" : column-value |
                       meta-instruction-property    }

column-value  ::=  { "string-value" | number-value | null | "" }

The top-level JSON object contains 1 or multiple comma-separated json-table-sections.

Each json-table-section is a property name-value pair. The name refers to a table in the database. The value is an array of row-sections.  Each row-section represents a record in the table.

Each row-section is a collection of column-sections.

A column-section is a property name-value pair. The name corresponds to a column of the table. The value corresponds to the value stored in that column in the record represented by the row-section. A column-section can also be a meta-instruction-property. See Meta-instruction properties in JSON.

Table-name and column-name are double-quoted as shown in the syntax block.

Column-value is double-quoted in the case of a string value or date value, unquoted in the case of a number value, or (in the case of a NULL value) either the JSON null keyword or a double-quoted empty value.
