I'm doing a project to read Excel files from my phone and output the data to the screen.

This is how I try to do it:

    private fun readDataExel() {
        val file = Uri.parse("content://com.android.providers.media.documents/document/document%3A1000007061")
        val inputStream = getContentResolver().openInputStream(file)
        //Instantiate Excel workbook using existing file:
        val workbook = WorkbookFactory.create(inputStream)

        //Get reference to first sheet:
        val sheet = workbook.getSheet("list")
        for (row in sheet) {
            if (row.getCell(0) == null || row.getCell(0).cellType == CellType.BLANK) {
                break
            }
            val codeValue = row.getCell(0).stringCellValue.toString()
            val liteCodeValue = codeValue.replace(".", "").replace("-", "")
            val articleValue = row.getCell(1).stringCellValue.toString()
            articles.add(ArticleModel(
                code = codeValue,
                liteCode = liteCodeValue,
                title = articleValue
            ))
        }

I get an error when I try to convert a uri to an Inputstream.

error in my logcat

I'm trying to get an Ecxel file (.xlsx) from my phone and read the data from the file.

I've Googled a lot and watched youtube videos, but I haven't found a solution to my problem.

Thanks for the help
