Working, NOT WORKING, Working – Google Sheets Review

Seems to indiscriminately work with (OR NOT) simple Excel files. Worst part - will not tell me what is incompatible so I can fix it once in Excel (on my other desktop computer) and then use my portable device to work with the file on the road. To be fair, when “Sheets” does work properly, it is useful. MariettaDave
