+# EasyAreaAlias
+
+### A FreCAD macro to create Aliasis for a selected range of cells from the row and column headings
+
+## Installation
+
+See [How to install macros](https://wiki.freecadweb.org/How_to_install_macros)
+
+## Usage
+
+### 1. Create a data-table
+
+In a FreeCAD spreadsheet create a data-table with row- and column-headers.
+
+Eg. have the part-name in the rows and in the columns the dimension category.
+
+| |X|Y|Z|
+|---------|---------|---------|---------|
+|Part 1|10|20|30|
+|Part 2|20|30|10|
+|Part 3|40|30|30|
+|Part 4|60|50|20|
+|Part 5|30|60|60|
+
+
+### 2. Select the data
+Select the data only, excluding the headings
+
+### 3. Execute the macro
+
+The macro will now check **and correct**[^1] the headings (replace specail characters, blanks, etc.) so that a proper alias can be generated and generate and set the alias for each cell in the selected range.
+
+Eg. in the tabel above the first cell will get the alias
+"Part_1_X", and so on.
+
+
+
+
+
+
+[^1] The corretiong is done to assure there are no differencies between the displayed text and the generated alias.
