However, Power Query ignores them because the column names are usually specified manually in the code. This creates additional difficulties when updating the dataset.<\/p><p><strong>How to solve this problem?<\/strong><\/p><p>Use a dynamic approach to handling columns:<\/p><ul><li>Dynamic column list. Instead of hard-coding column names, an automatic list is created that includes all available columns when the data is updated.<\/li><li>Formula Table.ExpandTableColumn. Formula allows you to dynamically expand columns in Power Query, taking into account all new columns in the data source.<\/li><\/ul><p>To learn more about how to set up dynamic column expansion in Power Query, please follow the link to <a href=\"https:\/\/careers.epam.ua\/blog\/how-to-dynamically-expand-columns-in-powerquery?utm_source=Facebook.com&amp;utm_medium=social&amp;utm_campaign=how-to-dynamically-expand-columns-in-powerquery&amp;utm_id=post&amp;utm_content=ta-ua\" class=\"external external_icon\" rel=\"nofollow noopener\" target=\"_blank\">the full EPAM article with step-by-step instructions.<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>When working with Power Query, you often encounter a situation where new columns are added to a data source.
