Managing large Excel files in WPS Office can be challenging due to performance issues if not handled properly. To ensure speed and seamless workflow, it is essential to follow a set of optimized techniques tailored to WPS Spreadsheets. First, always save your file in the newer Excel format rather than the older .xls format. The newer format uses efficient storage and is far superior at handling large datasets, which minimizes storage usage and accelerates opening.
Additionally, avoid embedding overused visual elements such as excessive colors, decorative lines, or complex rule sets across entire columns, as these drastically reduce recalculations and screen updates.
Minimize the use of recalculating formulas like OFFSET, especially in large datasets. These functions recalculate with every change, which can cause notable lag. Instead, opt for hardcoded entries where possible or use non-volatile alternatives. Similarly, replace CSE formulas with named ranges or pivot tables when applicable, as they are more memory efficient and more stable under load.
Break large workbooks into smaller, related files. If a single workbook contains independent tables, consider splitting them into distinct documents and linking them using worksheet connections or WPS’s data connection features. This reduces the memory footprint and allows you to open only the necessary sheets when needed. Use external data sources such as SQL servers and connect to them via WPS’s Data Connection Wizard instead of copying massive datasets directly into the spreadsheet.
Remove any blank rows and blank columns. Even if they appear clear, they may contain invisible styles that bloat the file. Select the full blank region, right click, and choose Remove to completely eliminate them. Also, clear any cell contents that are no longer needed, as empty cells with formatting still count toward the file’s complexity.
Enable manual formula updates in WPS Spreadsheets by going to Formulas > Calculation Options > Manual. This prevents automatic recalculation after every edit, which is particularly beneficial when working with thousands of formulas. Trigger calculations manually by pressing Ctrl+Alt+F9 when you need an update. This quick setting can greatly enhance speed.
Use filters and data pivots to analyze data instead of manually sorting. Pivot tables summarize large datasets efficiently and allow dynamic filtering without altering the original data. They also reduce the need for nested functions and help maintain data integrity. Always keep your source data organized, properly formatted in a structured range, and avoid merging cells, as they disrupt data integrity.
Regularly audit your file for broken links, duplicate data, or inconsistent data types. Use WPS’s Search and Replace to detect and resolve faulty data. Also, validate data using input restrictions to prevent users from entering that could lead to calculation errors.
Backup your files consistently and use versioning. WPS offers automatic saving and cloud sync features; make sure they are activated to avoid corruption. Additionally, save dated copies of your file with version numbers to document updates over time. Avoid sharing large files via email; instead, upload them to file-sharing platforms and share links to improve collaboration.
Finally, keep your WPS Office software current. Newer versions often include performance improvements, stability patches, and improved RAM handling for large files. Running old versions can lead to frequent freezes. By following these practices regularly, you can maintain optimal performance, minimize mistakes, and ensure that your large Excel files remain manageable within WPS Office.
