Convert Column Index to Corresponding Column Letter
Google Sheets provides a convenient way to represent data in a tabular format. Each cell within a spreadsheet is assigned a specific coordinate consisting of a row and column. The column is typically indicated using a letter (e.g., "A", "B", "C", etc.).
Converting Column Index to Column Letter
In certain scenarios, converting a numeric column index to its corresponding letter value becomes necessary. For instance, if you wish to reference a specific cell within a formula or script, it's essential to use the appropriate column letter.
The provided JavaScript functions offer a solution to this problem:
columnToLetter(column): This function converts a column index to its corresponding letter value. For example, 4 will return "D", 1 will return "A", and 6 will return "F".
letterToColumn(letter): This function performs the reverse operation, converting a column letter to its corresponding index. For example, "D" will return 4, "A" will return 1, and "F" will return 6.
