I'm trying to upload/import a 7 MB .csv file to Google Sheets without much luck.
What's the largest file size that you can import?
Spreadsheets: 400,000 cells, with a maximum of 256 columns per sheet. Uploaded spreadsheet files that are converted to Google spreadsheets format can’t be larger than 20MB, and need to be under 400,000 cells and 256 columns/sheet.
- 40,000 of your cells can have formulas.
- Certain formulas have their own specific limits, too, to make sure that even complex spreadsheets stay fast.
- Up to 1,000 GoogleFinance formulas
- Up to 1,000 GoogleLookup formulas
- Up to 50 Cross-workbook reference formulas and/or Functions for external data.
- VLOOKUP and HLOOKUP formulas tend to be more complex than other formulas. If your spreadsheet is slowing down or you think you may be approaching limits, you may want to remove some of these formulas.
- To determine the number of responses that a form can take, you need to take into account the number of questions in your form and the number of other cells of data within your spreadsheet.

So your file size doesn't seem to be an issue - maybe it is the number of columns and/or cells?
As of July 2019, my own experimentation says that:
A csv file of ~ 300000 cells, ~ 80 MB, was imported properly.
A csv file of ~ 700000 cells, ~ 100 MB, was not allowed to be imported.
I wasn't able to find any official documentation on this feature, but the import dialog will properly inform you if the .csv is "too large".
