Replace

The "replace" function is a data manipulation operation that substitutes specific values or patterns within a dataset, typically applied to text strings. It can be helpful for cleaning, formatting, or standardizing data by replacing occurrences of a specific value or pattern with another value.

The replace function typically takes two arguments:

• The old value or pattern is to be replaced.
• The new value will replace the original value or pattern.

Here's an example of using the replace function on a text column in a dataset:

Dataset:

Suppose you want to replace "Prod" with "Product" in the Product column. After applying the replace function, you'll get:

Updated dataset:

In Octai, you can use built-in string functions or operations to apply the replace function to your data. This function is particularly useful when you need to clean or preprocess your data before performing further analysis, ensuring consistency and compatibility across your dataset.
