The problem might arise because of the meta-text in the <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, &quot;Lucida Console&quot;, &quot;Liberation Mono&quot;, &quot;DejaVu Sans Mono&quot;, &quot;Bitstream Vera Sans Mono&quot;, &quot;Courier New&quot;, monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: var(--black-075); white-space: pre-wrap;">.csv</code> or <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, &quot;Lucida Console&quot;, &quot;Liberation Mono&quot;, &quot;DejaVu Sans Mono&quot;, &quot;Bitstream Vera Sans Mono&quot;, &quot;Courier New&quot;, monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: var(--black-075); white-space: pre-wrap;">.txt</code> file that is not really written there but is copied when its content is loaded somewhere.

I think it is better to first import your text in an array or a string and then split it and save into the dataframe specifically when your data is not too large.

Then take a look at arrays[:10] to find where the meta data ends and delete the unwanted data (meta data) and then converting the 'arrays' array into the dataframe. for instance:
