Today may 2nd, 2016. Since last week it is impossible to connect to my spreadsheets.
web site links don't work.
I have lost all my job.
I sent a mail to support but no answer

No answers anywhere I can see. Multiple people saying their files are coming up as "invalid" .... come on .... at least give some answers.

I inserted a a column and now i can delete it and I don't understand why

I want to use this to create an online calculator by publishing the spreadsheet as a widget to a webpage.
At the moment when using the widget, the cells cannot be edited in the widget, but only if the user opens the document via the widget.
It would be a great feature to be able to define areas/cells in the spreadsheet as interactive so that the widget user can edit data in these areas/cells. Also the widget should then do the formula calculatoins when data is changed in the interactive fields.

I want to use this as an online calculator but I dont want the hassle of creating a form and work with a database. So I just want to publish a spreadsheet with an area for data entry / possibility to enter data and an area with formulas.
To this end the user should only be able to edit the data area and not be able to touch the formulas. So the formulas should be protected - smilar to protected cells function in excel.

Everytime I click save, it opens a dialogue box and tells me the doc has been saved but when I reopen it, the values are reset to the original ones, before the editing!

I used this platform for a week suddenly before this new error popped up. Please help me by solving this so I can resume using this useful resource.

I have entered dozens of cells as numbers when they are really text. MS Excel has a way to convert a cell from numeric to text. I only see a GENERAL cell type option.

What am I missing?

i am getting error message - saving failed after trying to save spreadsheet

this is not a idea i have tried organizing the informatin on my spreadsheet by date but when i do dates get switched around. Please help with this.+
