Hi,
I was playing around with the Excel connector and created a list in Grasshopper.
Receiving that in Excel takes about 4 long minutes for about 450 rows with 4 columns each.
Is that the expected performance or is there something wrong with my setup?
Cheers,
Til
Thatâs definitely not the expected behavior!
Any chance you can share a sample stream for us to debug?
I created a test stream here: Speckle (for some reason I can´t access speckle.xyz with my speckle connector, but the data should be the same as in the example from yesterday)
A few things I noticed:
If I use âReceive last selectionâ it only takes a few seconds
If I receive the root object it also only takes a few seconds
I want my data to come through properly formatted though (which it doesn´t if I receive the root object)
Thus I had to ârewireâ my speckle objects in GHâŚ
and select the child of the root object (the list with 455 elements, see above) to get it into excel properly, which takes now only 2 long minutes not being behind a vpn todayâŚ
Hi,
another question related to the Excel connector. I have the following workflow:
Unfortunately step 5 fails with the error âInput object is not a Speckle object, nor can it be converted to one.â
Should that normally work?
Would it be possible to share with us the stream and excel sheet?
This should be supported but there may be some extra documenting needed on our side to clarify some things 
Hi,
I can´t create a ârealâ stream because somehow my Excel connector doesn´t work with speckle.xyzâŚ
I attached a .gh script to showcase how I create the initial stream and a Excel sheet to illustrate how it looks received in Excel.
fake data from attached script: Speckle
real data (can´t share the script): Speckle
speckle.xlsx (19.0 KB)
excel.gh (8.8 KB)
Hey @tlmn ,
I Just debugged the slowness issue, it seems to be because each element is detached and thatâs causing an extra API call. As a matter of fact, 455 * 0.15-0.3 sec results in approx 2 min.
Can you disable detaching on your source elements and try again?
Iâll also ping @dimitrie to see if itâs normal that the object loader takes so long to retrieve such simple objects. Ofc, the calls could be parallelized as wellâŚ
PS
Load last received works much faster as itâs pulling some cached data 
Normal receive:
Receive last selection:
Ok, for everyone else eventually reading this thread: setting ârange with headersâ in Excel did the trick (pretty obvious actually), now receiving in Grasshopper works like a charm 
Some more feedback on the Excel connectorâŚ
Can we make the connector remember the stream & branch of each individual sheet?
If you send to multiple branches in the same book, you most certainly end up sending to the wrong branches since it seems to pick the last used one (of a different sheet eventually).
Do you mean saving the stream cards per sheet instead of per workbook?
It can probably be done!
Do you mean saving the stream cards per sheet instead of per workbook?
Yes, exactly!
Good idea, tracked it here: Save streams per worksheet not workbook ¡ Issue #39 ¡ specklesystems/speckle-excel ¡ GitHub
Hey @tlmn ,
Good news! @connor and @gjedlicska have improved the receive logic and made the connector much faster; an update will come very soon!
