Office script: remove table if exists

Hi community, I'm new to power automate and office script - I'm hoping you can help

 

I am writing an office script to create a table in excel. When testing it in power automate it fell over because there was already a table in the file. To get round this I would like to check if there is a table and if so convert it to a range.

 

Here is my script so far:

 

function main(workbook: ExcelScript.Workbook) {

 

  // Get the current, active worksheet.
  let currentWorksheet = workbook.getActiveWorksheet();

 

  //If there is an existing table then remove it
  let existingTable = currentWorksheet.getTables()[0];

 

  existingTable.convertToRange();

 

  // Get the range containing all the cells with data or formatting.
  let usedRange = currentWorksheet.getUsedRange();

 

  // Log the range's address to the console.
  console.log(usedRange.getAddress());

 

  let newTable = workbook.addTable(usedRange,true);

 

  // Rename new table to "Table"
  newTable.setName("Table");
}

 

It works if there is an existing table but doesn't when there isn't one present. 

 

I found this where it it says it is possible to verify if an object is present but I do not know where to place the ? operator.

 

Can you help please?

    This works - I was dropping the period rather than keeping it. 

     

    Thank you for taking the time to reply, I appreciate it.

    here 

    existingTable?.convertToRange();

     

    Note that the best practices article you linked to also mentions you should use absolute sheet addressing.
