There's a new dialog on opening a file that says "Not liking how the file is displayed? Upload it temporarily to improve its display." Upload it WHERE? Where are you sending my private file? Why is there no option to view or remove uploads? The only option to the dialog box is OK. I clicked it on accident, it spun, and yes the file display improved, but now I have no idea where it sent my file. Seems like a terrible privacy violation.

Been using this app on a password protected file used as a password manager since last review in 2015 with no issues. (.ods file). Thanks to the last update, the formatting has gotten all messed up. Everthing got removed from multiple columns and merged sequentially across on a 1" wide space. It's almost like it's opening as a document file instead of a sreadsheet. Updated Review: Original problem has evidently been fixed. Changed rating to 4 stars.

Hi Gordon, thanks for your feedback! I'm sorry for the troubles the last update has caused. A new version is available now and it should work again as expected. Please let me know if it works for you now.

Works, kinda, but broken. Opened an ODT file, and everything worked perfectly. Wrote about two pages into it, saved it. Found the save was name (Invalid).ODT instead of the old filename. Tried to open it with with Word for Android, and it's corrupt. Reopened it with this, and it lost all formatting (paragraphs) in the application that wrote it. Renamed it and tried again after treating, and Word still won't open it (says it's corrupt), though this app can still see the text. Please fix!

I'm so sorry to hear you spent so much time editing your document only to end up in such a situation. Would you be able to share the corrupted file with us? That might give us a clue what went wrong. You can reach us at
