Available formats
The A1 format uses a letter followed by a number. The 1A format reverses that order. The 1,1 and reversed 1,1 formats use numbers only, either row-column or column-row.
Grid coordinates
Convert a message to grid coordinates, or coordinates back to a message.
Codes
Build a custom grid, choose a coordinate format, then convert a message to positions or read a coordinate sequence to extract text.

Quick explanation
Add the text that fills the grid, set the number of columns and rows, then choose the conversion direction. The tool can produce or read coordinates such as A1, 1A, 1,1 or reversed 1,1, with a setting to place letters on columns or on rows.

Additional information
Understand grid coordinates
A grid coordinate identifies a cell from two references: a row and a column. Depending on the convention, letters can represent columns, as in a spreadsheet, or rows, as in some game, puzzle or lookup grids.
The tool lets you choose the coordinate format and, when letters are involved, the letter axis. With headers enabled, the grid displays the exact references used to produce or read positions.
Letters on columns or rows
By default, A1 means column A and row 1. If letters on rows is enabled, A1 means row A and column 1 instead. This setting is disabled for numeric-only formats.
Text to coordinates
The entered text fills the grid in order, from left to right and then row by row. The tool then returns the position of each character using the selected format.
Coordinates to text
Paste a sequence such as A1 B1 C1 or 1,1 1,2 1,3. The tool reads the matching cells and rebuilds the message in the same order.
When to use it
This converter is useful for preparing a puzzle, checking a grid, turning a message into positions or quickly reading a cell-based code.
