Combining Multiple Tables based on Google Sheet as one list/table (Append)

Use Case:
A table based on a Google Sheet with less than 150,000 rows.

Limitations encountered:
Appsheet can only connect to a Google Sheet with 100,000 rows or less

Available Workaround:
Split the Google Sheet into two worksheets, making sure each worksheet doesn’t have more than 100,000 rows.

  • Import the two worksheets as separate tables
  • Use each worksheet as data partitions

Problems with the available workarounds
Users will need full access to the list, and switching between tables or partitions by using USERSETTINGS() or table expressions puts some limitations on some use cases where the tables are used as source for adding items to a child table using ref_rows (sub-form).

Proposed Solution
An ability where we can import the two worksheets separately, then an AppSheet feature where we can combine the two tables into one list which can be used as a source for a form.
It can be a new option in splice or whatever, as long as I can use the two tables together.
You can still impose a limitation to the total combined rows, maybe 300K rows (meaning upto three tables with 100K rows each)?

I don’t recommend that this feature will allow combining tables that reaches a million rows, or not even half a million rows. I agree that really huge datasets should be in a database server such as an SQL or a Google BigQuery, but the list is just 150,000 rows and is not expected to grow. Subscribing to a database server just because of the 50,000 rows over the limit will be overkill and is not a practical cost.

I never heard this limitation. Where have you heard this from ?

My understanding Spreadsheet has limit to max 5 mil cells, not row limits.

I saw this in many posts in this community. Just do a search for the keyword “100,000” and you’ll see them quickly. I didn’t pay much attention until I experienced it myself. I have a customer list which is 150K rows.

If I add that sheet as source to table, Appsheet will cause errors.
If I split that into two sheets with less than 100K each, then I can add the two sheets as separate tables: one table with 100K rows, and another table with 50K rows. No Issues.

But if appsheet can import the two sheets totalling to 150k rows anyways, why can’t I just import it as one table? But seems that it’s not possible, so I’m asking if there’s a way that I can just combine the two separate tables into one.

Jsut read the table (add table to your app) with the same schema, but just few rows only.
Once you managed to read this table, then swap the table soruce to your original one with rows more than 100k.

I tried this already. It will work when I fetch the fewer rows. Once synced, I change the worksheet and point it to the one with more than 100K rows, then the app would throws errors. I switch it back to the fewer row sheet, and it goes back working properly again.

We tested with our apps, and it works fine.
Not sure why you see error, maybe better to ask support@appsheet.com then.

How many columns and how many rows do you have in the Sheet?
I have 9 columns and less than 150k rows.

And even if I only have data in 1,000 rows, as long as the total rows, even when blank, exceeds 100,000, AppSheet throws the error.
