Convert chart to image
Excel API : ConvertChartToImage
Overview
Converts a chart of spreadsheet on a local drive to image.
Function Description
This method reads a chart of spreadsheet file from the local file system, converts it into the desired image format (e.g., PNG, SVG, Tiff), and returns the converted result. The source file path and target format must be specified correctly. Ensure that the necessary permissions are in place to read the source file and write the converted file if applicable. The conversion process occurs entirely on the cloud server, eliminating the need for any cloud storage or external downloads. If the source file does not exist, is inaccessible, or if an error occurs during the conversion process, an appropriate exception will be thrown. Supported formats for conversion depend on the available libraries and their capabilities.
