Hello,
I'm trying to export a very simple circuit board for production and SMT assembly and am not able to get it to work.
The Gerber works as expected but when I try to import the BOM/pick and place into JLCPCB I get an error message saying:
"No valid content found."
The BOM is as follows:
```
ID	Name	Designator	Footprint	Quantity	Manufacturer Part	Manufacturer	Supplier	Supplier Part	LCSC Assembly
1	S3B-XH-A-1 (LF)(SN)	CN1,CN2	CONN-TH_S3B-XH-A-1 (LF)(SN)	2	-	JST Sales America	LCSC	C163036
2	WS2812C	LED1	LED-SMD_4P-L5.0-W5.0-BL	1	WS2812C	Worldsemi	LCSC	C114587	Yes
```
And the pick and place:
```
Designator	Footprint	Mid X	Mid Y	Ref X	Ref Y	Pad X	Pad Y	Layer	Rotation	Comment
"LED1"	"LED-SMD_4P-L5.0-W5.0-BL"	"24.38mm"	"78.23mm"	"24.38mm"	"78.23mm"	"25.88mm"	"75.73mm"	"B"	"0"	"WS2812C"
"CN1"	"CONN-TH_S3B-XH-A-1 (LF)(SN)"	"31.75mm"	"78.23mm"	"31.75mm"	"78.23mm"	"31.75mm"	"80.73mm"	"T"	"90"	"S3B-XH-A-1 (LF)(SN)"
"CN2"	"CONN-TH_S3B-XH-A-1 (LF)(SN)"	"17.15mm"	"78.23mm"	"17.15mm"	"78.23mm"	"17.15mm"	"75.73mm"	"T"	"270"	"S3B-XH-A-1 (LF)(SN)"
```
I would expect this to work easily or without any intervention from the user so I've placed this into the bug report section.
Any tips?
