## Using double quotation marks in formulas

To include a text string in a formula, place the text string between two double quotation marks (") and Calc takes the characters in the string without attempting to interpret them. For example, the formula ="Hello world!" displays the text string Hello world! in the cell, with no surrounding double quotation marks.

The more complex formula =CONCATENATE("Life is really simple, "; "but we insist on making it complicated "; "(Confucius).") concatenates three individual strings in double quotation marks, outputting Life is really simple, but we insist on making it complicated (Confucius).

To place a literal double quotation mark within a string inside a formula, two methods can be used:

1. You can "escape" the double quotation mark with an additional double quotation mark, and Calc treats the escaped double quotation mark as a literal value. For example, the formula ="My name is ""John Doe""." outputs the string My name is "John Doe". Another simple example is the formula =UNICODE("""") which returns 34, the decimal value of the Unicode quotation mark character (U+0022) — here the first and fourth double quotation marks indicate the beginning and end of the string, while the second double quotation mark escapes the third.

2. You can use the CHAR function or the UNICHAR function to insert a double quotation mark. For example, the formula =UNICHAR(34) & "The Catcher in the Rye" & UNICHAR(34) & " is a famous book by J. D. Salinger." displays the string "The Catcher in the Rye" is a famous book by J. D. Salinger.

Be aware that Calc's AutoCorrect function may modify double quotation marks. AutoCorrect should not change the double quotation marks within formula cells but may change those used in non-formula cells containing text. For example, if you copy a string that is surrounded by some other form of typographical double quotation marks, such as the left double quotation mark (U+201C) and the right double quotation mark (U+201D), and then paste into a formula cell, an error may result. Open the Double Quotes area of the Tools - AutoCorrect Options - Localized Options dialog to set the characters used to automatically correct the start and end typographical double quotation marks. Uncheck the Replace toggle button to disable the feature.

## Empty string and blank cells

Cells with the empty string ("") are not equivalent to blank cells. When searching or calculating with text, the empty string "" is the text with length zero.

For example, when the formula in A1 returns the empty string "", the following applies:

=ISBLANK(A1) returns FALSE. The cell is not blank.

=ISFORMULA(A1) returns TRUE. The cell is a formula.

=ISLOGICAL(A1) returns FALSE. Not a logical value.

=ISNONTEXT(A1) returns FALSE. The cell has the empty string.

=ISNUMBER(A1) returns FALSE. Not a number.

=ISTEXT(A1) returns TRUE. The cell has the empty string, calculated by a formula.

=LEN(A1) returns 0. The length of the empty string is 0.

## ARABIC

Returns the numeric value corresponding to a Roman number expressed as text.

## ASC

Converts double-byte (full-width) characters to single-byte (half-width) ASCII and katakana characters.

## BAHTTEXT

数値を、タイの通貨名を含むタイ語のテキストに変換します。

## BASE

Converts a positive integer to a specified base into a text from the numbering system. The digits 0-9 and the letters A-Z are used.

## CHAR

## DECIMAL

Converts text that represents a number in a numeral system with the given base radix to a positive integer. The radix must be in the range 2 to 36. Spaces and tabs are ignored. The Text field is not case-sensitive.

## DOLLAR

Converts a number to a string representing the amount in the currency format, rounded to a specified decimal places, using the decimal separator that corresponds to the current locale setting. In the Value field enter the number to be converted. Optionally, you may enter the number of decimal places in the Decimals field. If no value is specified, all numbers in currency format will be displayed with two decimal places.

## EXACT

## REGEX

Matches and extracts or optionally replaces text using regular expressions.

## REPLACE

この関数は、文字列の一部を、別の文字列に置き換えます。文字列または数値の一部分を置換します。結果は常に文字列で返るため、数値は自動的に文字列としての数に変換されます。置換された数値を計算に使うには、戻り値を VALUE 関数で数値に変換する必要があります。
