MDX formats
This page lists all available MDX formats for the FORMAT_STRING
cell property, along
with their support in Atoti.
The official documentation for the formats can be found on the Microsoft website.
Introduction
The FORMAT_STRING
cell property specifies how to format both string and raw numeric
values. The following tables detail the syntax and the available formatting
characters that can be used for the property.
Atoti uses the FORMAT_STRING
cell property to format the VALUE
, storing the
formatted value in the FORMATTED_VALUE
cell property.
This behavior conforms to Microsoft's specification regarding these properties.
On the client's side, Atoti UI directly uses the formatted values from the
FORMATTED_VALUE
cell property.
Excel behaves differently for measures and does the formatting on the client, ignoring
the FORMATTED_VALUE
cell property.
This implies that:
- formats that are unsupported or partially supported may still be rendered correctly in Excel.
- custom formatters defined within Atoti will be ignored.
The formatting of other formattable elements such as dimension members behaves the same way both in Excel and Atoti UI.
The following symbols used throughout the page describe support in Atoti for the standard formatting syntax.
Symbol | Meaning |
---|---|
fully supported | |
partially supported | |
not supported |
Numeric Formats
When designating a numeric formatter, the format string must be enclosed with either
DOUBLE[]
or INT[]
(example: DOUBLE[#.###]
).
DOUBLE
and INT
can be used interchangeably. They accept the same format strings and
produce the same results.
Sections
A user-defined format expression for numbers can have anywhere from one to four sections, separated by semicolons. If the format argument contains one of the named numeric formats, only one section is allowed.
Format | Supported | Description |
---|---|---|
One section | The format expression applies to all values. | |
Two sections | The first section applies to positive values and zeros, the second to negative values. | |
Three sections | The first section applies to positive values, the second to negative values, and the third to zeros. | |
Four sections | The first section applies to positive values, the second to negative values, the third to zeros, and the fourth to null values. |
Characters
The following table lists the characters that can appear in the format string for numeric formats.
Character | Supported | Description |
---|---|---|
None | Displays the number without any formatting. | |
0 | Represents a digit placeholder that displays a digit or a zero ( If the number has a digit in the position where the zero appears in the format string, the formatted value displays the digit. Otherwise, the formatted value displays a zero in that position. If the number has fewer digits than there are zeros (on either side of the decimal) in the format string, the formatted value displays leading or trailing zeros. If the number has more digits to the right of the decimal separator than there are zeros to the right of the decimal separator in the format expression, the formatted value rounds the number to as many decimal places as there are zeros. If the number has more digits to the left of the decimal separator than there are zeros to the left of the decimal separator in the format expression, the formatted value displays the additional digits without modification. | |
# | Represents a digit placeholder that displays a digit or nothing. If the expression has a digit in the position where the number sign ( The number sign ( | |
. | Represents a decimal placeholder that determines how many digits are displayed to the left and right of the decimal separator. If the format expression contains only number sign ( The actual character used as a decimal placeholder in the formatted output depends on the number format recognized by the computer system. Note: In some locales, a comma is used as the decimal separator. | |
% | Represents a percentage placeholder. The expression is multiplied by 100. The percent character ( | |
, | Represents a thousand separator that separates thousands from hundreds within a number that has four or more places to the left of the decimal separator. Standard use of the thousand separator is specified if the format contains a thousand separator enclosed in digit placeholders ( Two adjacent thousand separators, or a thousand separator immediately to the left of the decimal separator (whether or not a decimal is specified), means "scale the number by dividing the number by 1000, rounding as required." For example, you can use the format string " The actual character used as the thousand separator in the formatted output depends on the number format recognized by the computer system. Note: In some locales, a period is used as the thousand separator. | |
: | Represents a time separator that separates hours, minutes, and seconds when time values are formatted. Note: In some locales, other characters may be used as the time separator. The actual character used as the time separator in formatted output is determined by the system settings on the computer. | |
/ | Represents a date separator that separates the day, month, and year when date values are formatted. The actual character used as the date separator in formatted output is determined by the system settings on the computer. Note: In some locales, other characters may used as the date separator. | |
E- E+ e- e+ | Represents scientific format. If the format expression contains at least one digit placeholder ( | |
- + $ () | Displays a literal character. To display a character other than one of those listed, put a backslash ( | |
\ | Displays the next character in the format string. To display a character that has special meaning as a literal character, put a backslash ( The date-formatting and time-formatting characters— The numeric-formatting characters— The string-formatting characters— | |
"ABC" | Displays the string inside the double quotation marks ( To include a string in format from within code, use Chr(34) to enclose the text. (The character code for a double quotation mark is 34.) |
Named Numeric Formats
The following table lists the predefined numeric format names.
Format name | Supported | Description |

Characters
The following table lists the characters that can appear in the format string for string formats.
Character | Supported | Description |
---|---|---|
@ | Represents a character placeholder that displays a character or a space. If the string has a character in the position where the at sign (@) appears in the format string, the formatted string displays the character. Otherwise, the formatted string displays a space in that position. Placeholders are filled from right to left unless there is an exclamation point (!) in the format string. | |
& | Represents a character placeholder that displays a character or nothing. If the string has a character in the position where the ampersand (&) appears, the formatted string displays the character. Otherwise, the formatted string displays nothing. Placeholders are filled from right to left unless there is an exclamation point (!) in the format string. | |
< | Forces lowercase. The formatted string displays all characters in lowercase format. | |
> | Forces uppercase. The formatted string displays all characters in uppercase format. | |

Note about Usable Formats
Internally, a java.text.SimpleDateFormat is used, so its formatting syntax must be used instead of the standard MDX syntax.
Using a format string that is incompatible with SimpleDateFormat
's expected syntax will
result in an exception in Atoti.
Example:
DATE[yyyy/MM/dd]
must be used to format dates asyear/month/day
, even though months should be designated with a lowercasemm
according to the MDX formatting standard.
Custom Formatters
Custom formatters can be added to Atoti by implementing the IFormatter
interface.
They can be useful to format Java objects that do not have formatting support by default
in Atoti, or to accept a different syntax than the one specified by the MDX
standard.
If the custom formatter needs to be configured with a pattern string, it should implement
IPatternFormatter
rather than IFormatter
. Similarly, the formatter can be provided
the current Locale
if it extends ALocalizable
.
In this case, the formatter should have a constructor with signature
Constructor([Locale], [String])
, depending on whether it extends ALocalizable
and/or
IFormatter
.
Once registered as a plugin value in the registry, the custom formatter can be used by
specifying its plugin key while defining a formatter (example: PLUGIN_KEY
or
PLUGIN_KEY[pattern]
, for a custom formatter whose plugin key is PLUGIN_KEY
).
