Performing Multiple Extraction

SmartExtract also supports extracting multiple data sets from a single pdf/xlsx file. There might be cases when your documents may have say multiple operating statements or operating statements and rent rolls in a single file. In such cases you could choose to launch multiple independent SmartExtract sessions to extract multiple data sets or you could launch a single session to let your users extract multiple datasets from single file in one go.

Using SmartExtract API

With SmartExtract API you could pass the option to start a multi-extraction session while calling the startSession API

smex.startSession(
  // the DOM element on which iframe should be mounted
  // e.g. document.getElementById('iframeWrapper'),
  mountNode,
  // The auth token you obtained after hitting the
  // authentication API,
  sessionAuthToken,
  // options, (optional)
  {
    // optional css classes to be applied to the iframe
    iframeClass: '<css classses to be applied to the iframe>',
    // start a mult-extraction session
    multiple: true,
  }
);

Using SmartExtractSimple API

With SmartExtract API you could pass the option to start a multi-extraction session while calling the extractDocumentData API

const data = await smex.extractDocumentData({
  session: {
    mountNode: $('#smexWrapper')[0],
    sessionAuthToken: token,
    closeOnComplete: false,
    // start a mult-extraction session
    multiple: true,
  },
  file: fileDataUrl,
  fileName: file.name,
});
