format	string	Yes	Format after conversion
str1	Any	Yes	Value 1 to be formatted
str2	Any	Yes	Value 2 to be formatted

Returned result
Formatted string.
Function example
- Test data: none
- Processing rule
```
e_set("result", str_format("{}={}", "lts", 8))
```

str1	Any (automatically converted to string)	Yes	Value 1 to be connected.
str2	Any (automatically converted to string)	Yes	Value 2 to be connected.

Returned result
Concatenated character string.

Function example

Test data: none

Processing rule

e_set("email", str_join("@", "lts", "aa", "com"))

Processing result
```
email:  lts@aa@com
```

str_zip

Format

str_zip(value1,value2,combine_sep=None,sep=None,quote=None,lparse=None,rparse=None)

Parameter description

Parameter	Type	Mandatory	Description
value1	Any (automatically converted to string)	Yes	Values to be combined.
value2	Any (automatically converted to string)	Yes	Values to be combined.
combine_sep	Any (automatically converted to string)	No	Identifier for combining elements. The default value is #.
sep	Any (automatically converted to string)	No	Separator between elements after combination. Only a single character is supported. The default value is ,.
quote	Any (automatically converted to string)	No	Character used to enclose combined elements. This parameter is required when the value contains a separator. The default value is ".
lparse	Any (automatically converted to string)	No	Separator and quotation mark between elements in value1. The default separator is , and the default quotation mark is ". The format is lparse =(',', '"'). Note: The quotation mark takes precedence over the separator.
rparse	Any (automatically converted to string)	No	Separator and quotation mark between elements in value2. The default separator is , and the default quotation mark is ". The format is rparse =(',', '"'). Note: The quotation mark takes precedence over the separator.

Returned result
Combined character string.

Function example

Example 1: sep usage.

Test data

{
 "key1": "value1,value11",
 "key2": "value2,value21"
}

Processing rule

e_set("combine", str_zip(v("key1"), v("key2"), sep="|"))

Processing result

key1: value1,value11 
key2: value2,value21 
combine: value1#value2|value11#value21

Example 2: Use of quote.

Test data

{
  "key1": "\"value1, value2\", value3, \"value4,value5\"",
  "key2": "value11,\"value12,value13\",value14"
}

Processing rule

e_set("combine", str_zip(v("key1"), v("key2"), quote='|'))

Processing result

key1: "value1, value2", value3, "value4,value5"
key2: value11,"value12,value13",value14 
combine: |value1,value2#value11|,|value3#value12,value13|,|value4,value5#value14|

Example 3: Values of different lengths.

Test data

{
 "key1": "value1,value2",
 "key2": "value11,value12,value13"
}

Processing rule

e_set("combine", str_zip(v("key1"), v("key2")))

Processing result

key1: value1,value2 
key2: value11,value12,value13 
combine: value1#value11,value2#value12

Example 4: Usage of lparse and rparse.

Test data

{
 "key1": "|value1, value1|, value2, |value3,value3|",
 "key2": "value11, #value12,value12#, value13"
}

Processing rule

e_set("combine", str_zip(v("key1"), v("key2"), lparse=(",", '|'), rparse=(",", '#')))

Processing result

key1: |value1, value1|, value2, |value3,value3|
key2: value11, #value12,value12#, value13
combine: "value1,value1#value11","value2#value12,value12","value3,value3#value13"

Function example

Test data
```
{
 "key1": "value"
}
```
Processing rule
```
e_set("str_sort", str_sort(v("key1")))
```

```
key1: value 
str_sort: aeluv
```

```
data: switch 
reverse_data: hctiws
```
