FINDB function

The FINDB function in Jspreadsheet Formulas Pro locates the position of a specific string of text within another string, taking into account case sensitivity. Unlike FIND, FINDB counts each double-byte character as 2 when DBCS is enabled. The unique aspect of this function is that the search begins from the right side of the string, rather than the left. This can be particularly useful when you're trying to locate specific text within a larger string.

Documentation

Returns the position of a string within another string, with case-sensitive matching. Counts double-byte characters as 2 when applicable.

Syntax

FINDB(find_text, within_text, start_num)

Parameter	Description
`find_text`	The text to find.
`within_text`	The text to search within.
`start_num`	Optional. The starting position of the search. If omitted, search starts at the end of the string. Defaults to 1 and is counted in bytes for DBCS-enabled contexts.

Behavior

The FINDB function in spreadsheets is used to search for a specific text string within another text string, and returns the starting position of the first text string from the first character of the second text string.

If the text string to be found is not found, the FINDB function returns a #VALUE! error.
If the start_num argument is omitted, it is assumed to be 1. If start_num is less than 1, FINDB returns a #VALUE! error.
If start_num is greater than the length of within_text, FINDB returns a #VALUE! error.
FINDB is case sensitive and does not allow wildcard characters.
FINDB counts each double-byte character (DBCS) as 2 when working in languages that use DBCS encoding; otherwise, each character counts as 1.
If any of the arguments are empty cells, FINDB will return a #VALUE! error.

Common Errors

Error	Description
#VALUE!	This error occurs when the text to find is not in the within_text or if the start_num is less than 1 or greater than the length of the within_text. It also occurs when any of the arguments are empty cells.

Best practices

Always ensure that the text to find is present within the within_text to avoid a #VALUE! error.

Be aware that FINDB is case sensitive, so be sure to use the correct case when searching for a text string.

Keep in mind that FINDB does not support wildcard characters.

Remember that FINDB counts each character as 2 if you have enabled the editing of a language that supports DBCS and then set it as the default language. Otherwise, it counts each character as 1.

Usage

A few examples using the FINDB function.

FINDB("o","Hello World") → Returns 5 (position in bytes; counts each single-byte character as 1)
FINDB("O","Hello World") → Returns #VALUE! (case-sensitive, no match)
FINDB("l","Hello World",3) → Returns 3 (first "l" after position 3)
