In Front-End our application, we use SpreadJS 16 to import excel (have shape in content). Then we send json data to server.
In Back-End, we use GrapeCity.Documents.Excel Ver 6.0.0 (FromJson() func) to get the json. And we receive the exception with message [String ‘1’ was not recognized as a valid Boolean]
After investigate, we recognize this issue come from the flipV property in Json string to be [“flipV”: “1”].
In normal case, the flipV (or flipH) should be True/False value.
Please give us some solution or some option for flipV (or flipH) be able to passed Json string with FromJson() func.
