xlpEXTRACT
Extracts desired characters and/or digits from a number or text.
Requires the 5,000 SD edition of xlPrecision or higher, or the Free Edition.
Syntax
xlpEXTRACT(num,numlist...,format)
| num | Required. The
number or text from which to extract desired characters and/or digits. num does not appear in Microsoft Excel's 'Insert Function' dialog. Instead, the first numlist argument is considered the num argument. If the first numlist argument is a range of cells, then the upper-left cell is considered the num argument. |
|
| numlist... | Optional. The list of characters, text strings, and/or digits to exclude from num. Accepts up to 29 numlist arguments, or up to 28 if the optional format argument is used. | |
| format | Optional.
Determines formatting options (formatting negatives with parentheses instead
of a leading hyphen, adding thousands separators, adding currency symbol,
and formatting in exponential notation), and setting maximum significant
digits. Any argument that begins with the text "format:" (must include the colon at the end) is evaluated as a format argument. Each of the five format options can be used individually in separate arguments, or any number of them can be combined in the same argument. When combining multiple format options into one format argument:
Must be enclosed in double quotes ("") if included directly in an xlpEXTRACT argument. Double quotes are not necessary if the format argument references a cell in which the format argument is entered. May be included anywhere but first in the series of xlpEXTRACT arguments -- can be the second argument, or the last, or anywhere in-between. The format argument is not case sensitive. |

format value |
Result | |
| format:negative | If return value is
negative, it is formatted with parentheses ("()") instead of the default
leading hyphen ("-"). You can also format negatives with a red font. |
|
| format:thousands | Return value is formatted with thousands separators (commas in English). | |
| format:currency | Return value is formatted with the local currency symbol. The currency symbol will be added either to the beginning or to the end of the result, whichever is appropriate for the locale. | |
| format:exponent | Return value is formatted in exponential notation. | |
| format:MSD=n | Determines the maximum number of significant digits to be returned. Default is 100, or the user's custom maximum set in the About box, or the maximum number allowed by the edition of xlPrecision, whichever is less. | |

Examples of valid combination format values |

|
format:negative,thousands,currency,MSD=200 (recognizes negative, thousands, currency, and MSD=200) |
||
|
format: negative - thousands - currency - MSD=75 blah blah this
extra text is ignored (recognizes negative, thousands, currency, and MSD=75) |
||
|
format:negativethousandscurrencyMSD=1000 (recognizes negative, thousands, currency, and MSD=1000) |
||
|
FORMAT:NEGATIVE,THOUSANDS,CURRENCY,MSD=200 (recognizes negative, thousands, currency, and MSD=200) |
||
|
Format:Negative,Thousands,cUrReNcY,msD=200 (recognizes negative, thousands, currency, and MSD=200) |
||
|
format:MSD=200,thousands,negative,currency (recognizes MSD=200, thousands, negative, and currency) |
||
|
format:MSD=200 blah blah this extra text is ignored negative (recognizes MSD=200 and negative) |
||
|
format:currency,thousands (recognizes currency and thousands) |
||
| Examples of invalid combination format values | ||
|
format negative,thousands,currency,MSD=200 (missing colon (:) after "format") |
||
|
format = negative,thousands,currency,MSD=200 (missing colon (:) after "format") |
||
| Examples of partially valid combination format values | ||
|
format:negative,thousands,currency,MSD200 (recognizes negative, thousands, currency, BUT missing "=" after "MSD") |
||
|
format:negative,thousands,currency,MSD:200 (recognizes negative, thousands, currency, BUT missing "=" after "MSD") |
||
|
format:negative,thousand,currency,MSD=200 (recognizes negative, currency, and MSD=200, BUT "thousands" is misspelled as "thousand") |
||
|
format:negative,thousands,currency,MSD=1,000 (recognizes negative, thousands, currency, BUT MSD is recognized as 1, not 1000, because the comma (",") is not a numeric digit) |
||
Remarks
xlPrecision results are returned as text that look like numbers, not as values that Excel recognizes as numbers. This is because Excel would truncate the results to 15 significant digits if it recognized them as numbers.
format:negative, format:thousands, format:currency, and format:exponent are all ignored by the 25 SD edition of xlPrecision.
format:thousands and format:exponent ignored by the 35 SD edition of xlPrecision.
format:MSD=n is ignored if it is higher than the maximum significant digits allowed by the edition of xlPrecision.
Use format:MSD=n to increase calculation speed where desired. The lower the number used, the faster the calculation.
You can use the results of xlPrecision functions as the operands in other xlPrecision formulas without losing any precision, but using them as operands in Excel's arithmetic functions will truncate them to 15 significant digits.
Decimal symbols, thousands separators, and currency symbols are all localized. This means that an xlPrecision formula that returns "$1,234,567.89" in the USA will return "1.234.567,89 €" in Germany, "1 234 567,89 €" in France, "1 234 567.89 kr" in Estonia, and "1.234.567,89Lek" in Albania.
Depending on how many significant digits the edition of xlPrecision provides, the result may be too long to conveniently view. You can view the full result by right-clicking the cell and choosing Format Cells | Alignment | Wrap Text, and widening the column to the width of the screen. An easy way to view the full result without changing column widths or wrapping text is to right-click the cell, choose Copy, and then paste into Notepad or a word processor.
