variable inside brackets powershell [duplicate]

Question

I am struggling on this for hours now ...

Its a syntax question basically how do I make this work : $test = '{"Title": $name}' The $name is not recognize as a variable. this is a simple example the real line is here and the unrecognize var is the $li at the end:

Add-PnPPageWebPart -Page "Home.aspx" -DefaultWebPartType ContentRollup  -Section 3 -Column $counter -WebPartProperties '{"query": {"contentLocation": 4,"contentTypes": [1],"sortType": 1,"filters": [{"filterType": 1,"value": "","values": []}],"documentTypes": [1,2,3,10],"advancedQueryText": ""}, "listTitle": $li}'

Thanks to those who will help :)

Yes, switch the quotes to double quotes. Interpolation doesn't occur in single quotes. So either switch the quotes, or escape the double quotes """{...}""". — Abraham Zinala

In short: In PowerShell, only "..." strings (double-quoted aka expandable strings) perform string interpolation (expansion of variable values and expressions), not '...' strings (single-quoted aka verbatim strings). With "..." quoting, if the string value itself contains " chars., escape them as `" or "", or use a double-quoted here-string. See the conceptual about_Quoting_Rules help topics. — mklement0

Use a double-quoted here-string:

$test = @"
{"Title": $name}
"@

Or use a regular double-quoted string, and then escape the literal "'s, by either doubling them:

$test = "{""Title"": $name}"

... or by using a backtick `:

$test = "{`"Title`": $name}"
