 ## Limitations
 
-- Columns only from A to Z
-- First row is always header with values (not empty cells)
-- By default all columns considered as 'singleLine' text. To make them 'number' or 'date' corresponding formatting should be enabled for the column
-  - 'number' Format => Number => Number
-  - 'date' Format => Number => Date or Format => Number => Date Time
-- Boolean column should always provide value (cell can not be empty). Can be defined via checkboxes
-- Spreadsheet document shouldn't have empty row in between of rows with data, because pagination logic relies on it.
