Methods

Method	Description
`getColumnName`	Get the column letter based on a number. `jspreadsheet.helpers.getColumnName(columnNumber: Number) => String`
`getCellNameFromCoords`	Get the spreadsheet-like cell name from the coordinates. `jspreadsheet.helpers.getCellNameFromCoords(x: Number, y: Number) => String`
`getCoordsFromCellName`	Get the coordinates from the spreadsheet-like cell name. `jspreadsheet.helpers.getCoordsFromCellName(cellName: String) => [Number, Number]`
`shiftFormula`	Update all variables from a formula based on a shift of x, y positions. `jspreadsheet.helpers.shiftFormula(formula: String, x: Number, y: Number) => String`
`getTokensFromRange`	Extract the tokens from a range. `jspreadsheet.helpers.getTokensFromRange(range: String) => Array`
`getRangeFromTokens`	Get the range from an array of tokens. `jspreadsheet.helpers.getRangeFromTokens(tokens: Array) => String`
`getCoordsFromRange`	Get the coordinates from a range string. `jspreadsheet.helpers.getCoordsFromRange(range: string, adjust?: boolean) => [number,number,number,number]`
`getRangeFromCoords`	Get the range string such as A1:A9 from an array of numbers. `jspreadsheet.helpers.getRangeFromCoords(range: [number,number,number,number]) => String`
`createFromTable`	Extract the configuration to create a new spreadsheet from a static HTML element. `jspreadsheet.helpers.createFromTable(element: HTMLElement, options: Object) => Object`
`parseCSV`	Transform a CSV string into an array. `jspreadsheet.helpers.parseCSV(data: String, delimiter: String) => Array`
`getTokensFromCoords`	Get all token names from a range of coordinates. `getTokensFromCoords: (x1: number, y1: number, x2: number, y2: number, wsName?: string) => []`
