According to the ListMatch video, what type of file must you import in order to populate ListMatch?

Importing a file to populate ListMatch requires the use of a .CSV (Comma-Separated Values) file. This format is widely used for data exchange because it allows for structured data to be organized in a simple text format where each line represents a data record, and each field within that record is separated by a comma.

Using .CSV files is particularly beneficial for ListMatch as they can easily accommodate large datasets, making it more efficient to manage contact lists or any organizational data that needs to be matched or compared within the platform. The other file types, such as .XLSX, .DOC, and .TXT, do not typically support the same structured approach required for effective data importation and matching in this context. Excel files (.XLSX) are more complex and not optimized for direct import into systems like ListMatch, while .DOC files are meant for text documents and .TXT files do not inherently support the data structure required by ListMatch. Therefore, selecting a .CSV file ensures compatibility and proper data handling within the platform.
