Importing Data from Excel

error exist in this line:

 export function button1_click(event) {export function importButton_onClick(event) { 

you try to use one export inside of another, this is for sure wrong usage…

Copy and paste this instead of all you have in code section:

import wixData from 'wix-data';

export function importButton_onClick(event) {
  const items = JSON.parse($w("#textBox").value);
  const collection = $w("#collectionInput").value;
 
  items.forEach( (item) => {
    wixData.insert(collection, item)
      .then( (results) => {
        console.log(`Added item: ${JSON.stringify(results)}`);
      } )
      .catch( (err) => {
        console.log(err);
      } );
  } );
 
  $w("#textBox").value = "";
}

and, you need button with id “importButton” - and you should add “onClick” event on it
