You can use Office Scripts to achieve this.

For Run script I have
function main(workbook: ExcelScript.Workbook) {
const sheet = workbook.getWorksheets()[0];
let lastRow = sheet.getUsedRange(true).getLastCell().getRowIndex() + 1;
let rng = "A3:P" + lastRow
let tableTest = sheet.getRange(rng).getValues();
console.log(tableTest);
}
Then under Compose
@{outputs('Run_script')?['body']?['Logs'][0]}
Then Initialize the "RemoveString" variable
@{split(outputs('Compose'),' ')[0]}
Then Initialize the "NewString" variable
@{replace(outputs('Compose'),variables('RemoveString'),'')}
Then Run Script 2 and add "NewString" as the parameter.
function main(workbook: ExcelScript.Workbook, rangeTest: string) {
let table = workbook.getTable("BacklogTable");
let str = rangeTest;
let testerTest = JSON.parse(str);
table.addRows(null, testerTest);
}
The reason for RemoveString is to remove the Date & Time Stamp from the outputs
