One common task is to clean or modify strings based on particular patterns. In this guide, we’ll explore a user-defined function called LIMPA, designed to remove certain patterns from strings. We'll also troubleshoot and optimize it for more variety in inputs. The Problem: Incorrect String Processing The LIMPA function, as originally defined, aims to remove a time stamp (like "5:32 PM") from a string but doesn't work as expected. For example, when inputting the following string: [[See Video to Reveal this Text or Code Snippet]] The function returns the entire string rather than just the desired text ("Muitas letras"). Additionally, it throws an error when used as an array formula, which hampers its utility. The Original Function Here is the initial version of the LIMPA function: [[See Video to Reveal this Text or Code Snippet]] Immediate Issues Pattern Matching: The use of 0 for the last argument indicates that no matches should be performed, which leads to incorrect results. Array Formula: The function fails to handle multi-dimensional arrays effectively. The Solution: Enhancing the LIMPA Function To resolve these issues, we need to adjust the arguments provided to the REGEX function correctly and ensure that our user-defined function can also handle array inputs. Step 1: Adjusting the Function Call Change the last argument from 0 to 1 when calling REGEX to ensure it matches exactly one occurrence of the specified pattern: [[See Video to Reveal this Text or Code Snippet]] Step 2: Creating a Versatile Function To make the LIMPA function versatile enough to accept both single strings and arrays, we can use an auxiliary function. Here's how: [[See Video to Reveal this Text or Code Snippet]] Breakdown of the Code DoReplace Function: It simply wraps the actual regex call, enabling clean handling. LIMPA Function: This checks if the input is an array. If it is, it iterates through the array, applying the DoReplace function to each element. If not, it directly uses DoReplace. Optional Enhancements If you need the function to work for arrays that span multiple columns, you can extend the results array initialization. Here’s a snippet on how to adjust it: [[See Video to Reveal this Text or Code Snippet]] Conclusion: Empowering Your Spreadsheet Skills By implementing these changes, your LIMPA function will now be able to effectively strip away unwanted patterns from strings, while also being versatile enough to process multi-dimensional arrays. Understanding how to integrate user-defined functions with built-in capabilities like REGEX in LibreOffice Calc not only boosts your productivity but also enhances your spreadsheet’s capabilities to manage text data effortlessly.
