Description Dan Dascalescu 2017-11-21 16:51:41 UTC
Description:
I'm trying to SUBSTITUTE '"foo"' (including the double quotes) with "bar", but I can't find out how to escape the double quotes.

https://help.libreoffice.org/Calc/Text_Functions#SUBSTITUTE isn't helpful.

Steps to Reproduce:
=SUBSTITUTE(A1, "\"foo\"", "bar")

Actual Results:  
Err:508

Expected Results:
A1 with '"foo"' replaced by "bar".


Reproducible: Always


User Profile Reset: No



Additional Info:
Quoting the search text using single quotes doesn't work.

I was unable to achieve this.

According to this: https://wiki.documentfoundation.org/EscapingCharacters we express a single double quote by 4 double quotes in a row. Apparently this is the same in Excel.

I also found information that you can use CHAR(34) to express the double quote.

I tried:
=SUBSTITUTE(A1;"CHAR(34)fooCHAR(34)";"bar")

But it just gives me the contents of A1 unchanged.

I get the same result with 5 double quotes in a row:
=SUBSTITUTE(A1;"""""foo""""";"bar")
Comment 2 Eike Rathke 2017-11-22 18:01:05 UTC
4 double quotes is nonsense. In any literal string in formula expressions, a double quote is escaped by doubling it. The 4 quotes in the example are a literal string containing *one* quote, i.e. the enclosing double quotes and in the middle the escaped double quote.

For the example given here it should be
=SUBSTITUTE(A1, """foo""", "bar")

Comment 4 Dan Dascalescu 2017-11-22 18:18:53 UTC
Doubling the double quote works. Thank you.

My request is to add how to properly escape double quotes to the documentation for text functions at 
https://help.libreoffice.org/Calc/Text_Functions, since it's clearly not obvious, as the discussion about four double-quotes in this ticket proves.

My problem was because I had autocorrected typographic quotes in the string: ”foo”
