This is an effort to list all available functions that can be used in virtual formulas.
Additionally:When you scroll down a bit, you will find another section that lists functions that will become available to use in virtual tags after you have installed Boroda's fantastic Additional Tagging & Reporting Tools plugin.

Their workings:___
$Contains(<field>,search-value)
checks if a tag contains a given value, which can be a text string or a tag.
Returns 'T' or 'F' (true or false)
example:$Contains(<Genre>,rock)
will e.g. produce 'T' when the genre is 'Jazz-rock'By combining this function with the
$If function you can use it to output a custom text. (or the contents of another tag)
example:$If($Contains(<field>,search-value)="T",value1,value2)
(where value1 is produced when 'true' and value2 when 'false')___
$Count(<grouping-field>)
and
$Count(<field>,<grouping-field>)
returns the number of items in a defined group.
examples:$Count(<Album>)
returns the number of tracks of an album$Count(<Artist>)
returns the number of tracks of an artist$Count(<Album>, <Album Artist>)
returns the number of albums of an album artist___
$Date(<field>,format)
returns a date field using a defined formatting, using an existing date tag as the source.
examples:$Date(<Date Modified>,yyyy/MM/dd HH:mm)
(will e.g. output: 2021/12/31 19:30)$Date(<Date Modified>,MMMM yyyy)
(will e.g. output: december 2021)Relevant formatting options:
date: d / dd / ddd / dddd
month: M / MM / MMM / MMMM
year: yy / yyyy
hour: H / HH
minute: m / mm
(the letter count defines displaying 1 or 2 digits, abbreviated, full)___
$First(<field>)
returns only the first value of a multi-value tag.
___
$Group(<field>,n)
returns an alphabetical grouping string.
The number for 'n' defines the amount of alphabetical characters the alphabet will be divided in.
examples:For the artist 'Deafheaven':$Group(<Artist>,3)
the output will be: DEF$Group(<Artist>,4)
the output will be: ABCD___
$If(<field1>=<field2>,true-value,false-value)
returns one of two values depending on a comparison of two different tags.
For numerical tags, besides
= (equals), also
< (less than) and
> (greater than) can be used.
$And(Criterion1,Criterion2)
$Or(Criterion1,Criterion2)
are both subfunctions that can be used in combination with the $If function.
They make it possible to have two (or more) criteria being met before returning a true or false result.
for 'And', both criteria must be met to output 'T'
for 'Or', at least one criterium must be met to output 'T'
example: $If($Or($Contains(<Album>,live)=T,$Contains(<Title>,live)=T),Live,Studio)
(checks if any of two different tags contains the word 'live')tip:
As an alternative to using $Or, you can also line up two (or more) tags in $Contains.
example:$If($Contains(<Album><Title><Keywords><Genre>,live)=T,Live,Studio)
(will check if any of these four tags contains 'live', and if so will output 'Live'.)___
$IsMatch(<field>,regex-pattern)
checks if a tag matches a regular expression.
Returns 'T' if true or 'F' if false.
example:$IsMatch(<Artist>,"^The\s")
(will output 'T' if the Artist tag begins with 'The')___
$IsNull(<field>,value if empty,<field>)
checks if a tag is empty, and then outputs either that- or another tag, or a value that can be either a text string or a tag.
This can also be useful to prevent MusicBee from displaying 'Unknown' for tags used in a formula that are empty.example:$IsNull(<Album>,"",<Album)
(will display blank instead of 'Unknown' for tracks without an Album tag)___
$Left(<field>,n)
$Right(<field>,n)
'Left' returns the first 'n' count characters of a tag.
'Right' returns the last 'n' count characters of a tag.
___
$Len(<field>)
returns the amount of characters (length) of a tag.
___
$Lower(<field>)
$Upper(<field>)
converts a tag to all lower-case or all upper-case.
___
$Min(<field>,<grouping-field>)
checks for the item in a group that has the lowest value and outputs that value.
$Max(<field>,<grouping-field>)
checks for the item in a group that has the highest value and outputs that value.
examples:$Max(<Play Count>,<Album>)
(returns the highest play count that is found for any track(s) of an album)$Min(<Year (yyyy)>,<Artist>)
(returns the earliest year that is found for any track(s) of an artist)___
$Pad(<field>,n)
pads numerical tags to 'n' digits by adding zeros at the beginning.
example:Pad(<Track#>,3)
(will e.g. output '001' for track '1')___
$RemoveSortWords(<field>)
outputs the content of a tag while removing the 'ignore words' as defined at: Preferences > Sorting/Grouping.
So e.g. 'The Beatles' can be output as 'Beatles'.
___
$Replace(<field>,search-value,replace-value)
searches a tag for a defined search value, and replaces that value with a defined replace value.
$RxReplace(<field>,regex-pattern,replace-text)
does the same, but allows for using regular expressions.
example:$RxReplace(<Title>,"feat[\W\.]",ft.)
(replaces 'feat.' in a title with 'ft.')___
$RxMatch(<field>,regex-pattern)
returns the text portion that is matched by a regular expression.
example:$RxMatch(<Year>,"\d{4}")
(returns the year only, so it will e.g. produce '2021' for both '2021-12-31' and '31/12/2021')___
$RomanNumerals(<field>)
outputs a numerical field formatted as Roman numerals.
example:$RomanNumerals(<Movement #>)
(will e.g. display 'III' for '3')___
$Split(<field>,search-text,index)
returns a defined index section of a tag.
The search-text defines the index divider, the index is a number that counts the sections from left to right.
example:$Split(<Title>,:,3)
(will return 'Three' for a title being: 'One: Two: Three: Four')$RSplit(<field>,search-text,index)
does the same as $Split, but counts from right to left.
$RxSplit(<field>,regex-pattern,index)
does the same as $Split, but allows for using a regular expression to define the split value.
___
$Sort(<field>)
returns a tag in the format of a sorting field, moving 'Ignore words' (as defined at: Preferences > Sorting/Grouping) to the end of the tag.
example:$Sort(<Artist>)
(will output 'Beatles, The' for 'The Beatles')___
$Sum(<field>,<grouping-field>)
returns the total count of an item in reference to a group.
examples:$Sum(<Play Count>,<Artist>)
(returns the total play count for all tracks of an artist)$Sum(<Play Count>,<Album>)
(returns the combined play count for all the tracks of an album)___
$Trim(<field>)
removes any spaces from the beginning and the end of a tag.
