Hello,
I am using array formula function in my spreadsheet to auto-fill calculations when glide users fill a form. One of the array formula function need to be in time format (ex: HH:MM:SS) but when a new line is created the time format disappear and becomes a simple number (ex : 1,299990).
Does someone can help me ?
Thank you
Can you show what your arrayformula looks like?
Also, I would ask the question do you actually need this time column in your spreadsheet?
If the data is only used in Glide, then you might find that itâs better to calculate this in Glide using date math.
This is happening because you donât have rows under, so glide is actually adding a new row which is not formatted by Google, add more rows to that sheet, and in array formula delete second ââ
If(l2:l="", , l2:l - âŠ
If I have 100 rows under formatted by Google, Glide will create a new one after the 100 and the new one will not die formatted
Add 1000 or more
If you erase ââ from arrayformula, glide will add to next empty row
You need to change all your arrayformulas.
You are writing ââ to cellâs thatâs why glide considering those rows not empty and adding unformated new row.
Change your arrayformulas, and erase manually all empty rows (not delete⊠erase)
And always use this way to check empty rows:
=ARRAYFORMULA(IF(A2:A="", , B2:B - C2:C))
If I add 1000rows Glide create a row after these 1000.
With or without 33 glide create a new row with the array formula function
Erase all empty rowsâŠ
You need to find and change all arrayformulas in this sheet
The reason why Glide is adding a row after 1000 rows is because they are not empty, your arrayformulas writing ââ to these rows⊠fix all formulas in this sheet the way i show you (not only one formula, all of them)
I do exactly what you said: erase empty row by changing ââ by ;; on all array formula. I add 500 rows.
But it doesnât work 
By the way I find a solution but itâs not easy.
I create a new sheet and I enter â=arrayformula(âParcours en Etoileâ!M:M)â. On this sheet I change the format to time format.
Then on the first sheet I add a new column and I enter a new array formula to copy the second sheet. 
Why you using ; ?
Use ,
If is not working, you missed some formulas, and is still populating data
Or you have some filter or query formula there that is filling down columns with empty values
Other countries use â;â in place of â,â and vice versa.
