Functions
QString	csvQuote (const QString &value)
	Returns a CSV-safe quoted field: wraps value in double-quotes if it contains a comma, double-quote, or newline; embedded double-quotes are escaped as "".
bool	toCSV (QAbstractItemModel *model, const QString &filePath)
	Writes model to an RFC 4180 CSV file at filePath.
bool	toJSON (QAbstractItemModel *model, const QString &filePath)
	Writes model to a JSON file at filePath.

Detailed Description

Free functions that serialise any QAbstractItemModel to CSV or JSON.

Both functions operate on whatever rows and columns the model exposes — pass a QSortFilterProxyModel to export only the currently visible rows, or the raw source model to export everything.

Constraint: QtCore only — no widgets, no UI signals.

Function Documentation

csvQuote()

QString TableExport::csvQuote

(

const QString &

value

)

Returns a CSV-safe quoted field: wraps value in double-quotes if it contains a comma, double-quote, or newline; embedded double-quotes are escaped as "".

Exposed so other CSV writers outside this module (e.g. Graph's report writers, which build rows from data that never passes through a QAbstractItemModel) can reuse the same escaping rules instead of reimplementing them.

toCSV()

bool TableExport::toCSV	(	QAbstractItemModel *	model,
		const QString &	filePath )

Writes model to an RFC 4180 CSV file at filePath.

The first row is the column headers from headerData(). Each subsequent row is one model row. Fields containing commas, double-quotes, or newlines are enclosed in double-quotes; embedded double-quotes are escaped as "".

Returns

true on success, false if the file could not be opened/written.

toJSON()

bool TableExport::toJSON	(	QAbstractItemModel *	model,
		const QString &	filePath )

Writes model to a JSON file at filePath.

Produces a top-level JSON array of objects. Each object has one key per column, taken from headerData(), with the display-role cell value as the string value.

Returns

true on success, false if the file could not be opened/written.
