WPS Spreadsheet’s Power Query is a powerful tool designed to simplify and streamline the process of importing, transforming, and cleaning data from a wide variety of sources

Whether you are working with data from Excel files, wps官网 CSV documents, databases, web pages, or cloud services

Power Query provides an intuitive interface that requires no programming knowledge to perform complex data operations

First, open your spreadsheet and locate the Data ribbon to access Power Query tools

Click the Get Data option to reveal a comprehensive list of supported import types

Select from sources like Text

Each option walks you through a guided wizard to establish a secure and accurate connection

After choosing a source, the Query Editor opens to let you inspect the raw data before loading

You can verify data alignment, identify null fields, and correct inconsistent headers or data types before import

For instance, if your header row is incorrectly placed on row 3, just click to set it as the header row

Power Query automates data cleanup with remarkable efficiency

You can remove unwanted columns, split or merge text fields, change data types, filter out rows based on specific criteria, and even replace errors or blank values with defaults

Users without programming background can perform complex edits using only mouse clicks and dropdowns

Each transformation you apply is recorded as a step in the Applied Steps pane, allowing you to review, reorder, or delete any step at any time

One of the most valuable features of Power Query is its ability to refresh data automatically

A single Refresh button reconnects and updates your entire dataset, saving hours of repetitive work

Essential for reports that update daily, hourly, or on a scheduled basis from external sources

You no longer need to download, open, and copy-paste data from external files

You can consolidate datasets from various files, folders, or servers into a single cohesive table

For example, gather 12 monthly Excel files and combine them into one annual table in seconds

Link tables using primary keys like Account Number or Region Code to pull in extra details from external files

When working with large or complex datasets, Power Query helps maintain data integrity by applying consistent transformations across all imported files

It minimizes missteps and guarantees your conclusions rely on clean, uniform, and trustworthy data

You can copy the entire query to another file or send it to a teammate for immediate use

Once satisfied, select the Close & Load option to apply all changes and import the data

The cleaned dataset is inserted into your spreadsheet as a dynamic Excel table with full formatting

Select whether the output should appear in a new tab or overwrite an existing table

The imported table supports all standard Excel analysis tools, including charts, filters, and calculated columns

In essence, this feature transforms how professionals and students manage data from outside sources

The tool converts cumbersome data prep into an efficient, repeatable system

With its easy-to-use tools and powerful cleaning functions, you gain hours back and minimize data errors
