...
Please note that we did nothing except send the DBF table to the AI with a request for statistical analysis, and now we have the program.
I didn't program a single line of the whole program manually!
By the way, this PHP4DBF library largely uses FIVEWIN/HARBOUR syntax.
The next prompt is now the one where you automatically create a data.json from the DBF file, which is then displayed.
Here, I use my own development: the php4dbf library.
The prompt:
Can you provide me with source code to directly create the data.json using php4dbf?
Here the json from sourcecode:

**
* php4dbf Library

* - php4dbf_getDbfHeader: Retrieves the header of a DBF file.
* - php4dbf_getFieldDescriptors: Retrieves the field descriptions of a DBF file.
* - php4dbf_padValue: Properly pads values based on their type.
* - php4dbf_addRecordToDbf: Adds records to a DBF file.

* - php4dbf_getRecordByIndex: Retrieves a record by its index.
* - php4dbf_numrecords: Retrieves the number of records in a DBF file.
* - php4dbf_numfields: Retrieves the number of fields in a DBF file.
* - php4dbf_get_record_with_names: Retrieves a record with field names from a DBF file.
* - php4dbf_close: Closes a DBF file.
* - php4dbf_loadAllFile: Loads the entire DBF file into memory.
* - php4dbf_loadAllHeader: Extracts header information from the file content string.
* - php4dbf_readHeader: Reads header information from a file pointer.
* - php4dbf_extractFields: Extracts field descriptions from the loaded DBF file data.
* - php4dbf_readRecordByIndex: Reads a record based on the specified index.
* - php4dbf_closeDbfFile: Closes an open DBF file handle, if present.
* - php4dbf_openFile: Opens a DBF file and loads either the full content or just the header.
* - php4dbf_getLastUpdateDate: Extracts the last update date from the DBF header.
* - php4dbf_flock: Attempts to create a lock and lock file.
* - php4dbf_phpunlock: Releases the lock created by `flock` using PHP.
* - php4dbf_unlock: Releases the custom lock by deleting lock files.
* - php4dbf_updateField: Updates a specific field within a record in a DBF file.
* - php4dbf_updateLastModifiedDate: Updates the last modified date in the DBF header.
* - php4dbf_checkFileSizeConsistency: Checks file size consistency with the number of records.
* - php4dbf_appendBlank: Adds a blank record to a DBF file.
* - php4dbf_getHeader: Helper function for common header processing.
* - php4dbf_DBUse: Opens a DBF file and reads the header as well as the field descriptions.
* - FieldPos: Returns the 1-based position of a field by its name.
* - FieldName: Returns the name of a field by its 1-based position.
* - FieldPosLast: Returns the 1-based position of the last field.
* - php4dbf_dbGoTop: Moves the record pointer to the first valid record.
* - php4dbf_dbGoTo: Moves the record pointer to a specific record.
* - php4dbf_init: Initializes the DBF file for reading.
* - php4dbf_get_next_record: Reads the next record from the DBF file.
* - php4dbf_parse_record: Parses a record from raw binary data into an associative array.
* - php4dbf_convert_value: Converts a raw binary value to the appropriate data type based on field type.
