Boxes - AppendPrepend Value or Column or Assign Value
1. Static Value
This box is used to append, prepend or assign a static value to a cell. It won't add a whitespace before or after that value. When choosing to assign this static value to a cell everything will be replaced by that static value.
Example: You need a column with "Free shipping" as an information for the shipping cost.
Use Static Value to assign
"Free Shipping"
to that column.

2. Append/Prepend Value
This box is used to add fixed value(s) at the beginning or end of a cell. It also adds a whitespace before the value when you chose to append. When prepending the value a whitespace after the static value is added.
Example: Add "Free delivery!" at the end of the product description.
description before:
"Yourdomain basic T-Shirt blue. 100% Cotton, Size XL."

After using the box:
"Yourdomain basic T-Shirt blue. 100% Cotton, Size XL. Free delivery!"
3. Append/Prepend Value if not Empty
With this box you can append or prepend a value if the cell is not empty.
Example: Prepend the static brand name "Nike" to a column.
Shoes Black Women

After using the box:
Nike Shoes Black Women
4. Add Value if Fits
With the box Add Value if Fits you can append or prepend a value to a cell and fill in the maximum length of signs for that cell. The vaue will only be added if it fits into that length.

Example: You want to add "supersale" and append it to the values in the cell.
Choose in Mode if the text should be appended or prepended to the text in the column.
Fill in the Text in the input box for Text.
Fill in the number of signs the platform you are on allows you to assign in the input box for Max Length. (e.g. 70 signs for the title when exporting to Google Merchant Center)

5. Append/Prepend Column
This box is used to add the value(s) of a column included in your feed at the beginning or at the end of a cell. You also can enter a static text that should be before or after the dynamic value. If there is no dynamic value in the column the static value won't be added to the cell.As the box explained before, it also adds a whitespace before the value when you chose to append. When prepending the value a whitespace after the static value is added.
Example: Add the available size to the product description. There is a fixed value: "Size:", and a dynamic value: "13", as this changes according to each product.
description before:
"Yourdomain Biker boots brown. Upper material: leather, internal material: leather, sole: high-quality synthetics, cover sole: leather."

After using the box:
"Yourdomain Biker boots brown. Upper material: leather, internal material: leather, sole: high-quality synthetics, cover sole: leather. Size: 13"
Descending order
The order in which you place the rule boxes is very important. Productsup uses a descending order. This means that the box you place first, or at the top, will be executed before the boxes that follow.

This sequence will be:
"Size: 13 Free delivery!"

This sequence will be:
"Free delivery! Size: 13"
6. Append/Prepend Column if Value Not Present
This box works like Append/Prepend Columnbox, but checks first if the value is not present to avoid duplicates.
Example:
Title product A:
Nike Shoes Black Women
Color: Black
Title Product B:
Adidas T-Shirt
Color: Blue

After using the box:
Nike Shoes Black Women Adidas T-Shirt Blue
7. Add Column if Fits
This box is used to append or prepend a column to another column and fill in the maximum length of signs for that cell. The vaue will only be added if it fits into that length. You also can add a static text before or after the value of the added column.
