Covers practical node interaction controls (configure, execute, cancel, reset), labeling, dynamic ports, and execution states including errors. Summarizes key reader capabilities for CSV, Excel sheets, data tables, KNIME .table files, and Google Sheets, plus how relative file paths are handled. Also outlines common transform steps (grouping, pivoting, rule-based row processing, sampling, filtering, math operations, date parsing, splitting, column filtering, renaming/types, joining, sorting, merging, missing-value handling) and introduces analysis components like learners, scorers, and ROC/metrics.",{"@graph":14,"@context":73},[15,34,56],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/presentations/","Presentations",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/beginner-cheat-sheet-knime-51/572363/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/beginner-cheat-sheet-knime-51/572363.png","ImageObject",442,249,{"name":42,"@type":43},"นรินทร์","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-21","2026-10-13",true,{"@type":52,"interactionType":53,"userInteractionCount":55},"InteractionCounter",{"@type":54},"ViewAction",7,{"@type":57,"mainEntity":58},"FAQPage",[59,65,69],{"name":60,"@type":61,"acceptedAnswer":62},"What do the node action bar options configure, execute, cancel, and reset do?","Question",{"text":63,"@type":64},"Configure opens the configuration dialog.

Configure: Open the configuration dialog.  \nExecute: Executes the node.  \nCancel: Cancels the execution of the node.  \nReset: Resets the node.  \nNode Labels: Double click “Add comment” below the node to add a comment/label.  \nDynamic ports: Additional input ports can be added by clicking the plus on the left  \nside of the node.  \nNot configured: Node is not yet configured and cannot be executed with its current settings  \nConfigured: Node has been correctly configured and may be executed at any time  \nExecuted: Node has been successfully executed and results can be viewed and used in downstream nodes.  \nError: The node has encountered an error during execution.  \n\n| \u003Cbr>READ |  |  |  |\n| --- | --- | --- | --- |\n| | Reads CSV files.
