The following example works correctly on macOS/Linux, but not on Windows: ```javascript const Excel = require('exceljs'); const wb = new Excel.Workbook(); wb.addWorksheet('TOC').state = 'visible'; wb.addWorksheet('Test Sheet').state = 'visible'; const ws = wb.getWorksheet('TOC'); ws.getCell('A1').value = { text: 'Test Hyperlink', hyperlink: `#'Test Sheet'.A1` }; wb.xlsx.writeFile('output.xlsx'); ``` For the hyperlink value I have tried: ``` * `#'Test Sheet'!A1` * `#"Test Sheet"!A1` * `#'Test Sheet'.A1` * `#"Test Sheet".A1` * `#\\"Test Sheet\\"!A1` * `#\\'Test Sheet\\'!A1` * `#\\"Test Sheet\\".A1` * `#\\'Test Sheet\\'.A1` ``` and a few others. None work.
