There may be several reasons why the text copied from the Excel table is incomplete: If the format of the text box in the Excel table is different from the format of the pasted text box, the text content will be incomplete. For example, if the font color and size of the text box in the Excel table were different, or the color of the text box border was different, the pasted text content would be incomplete. 2. Limit of text length: Each text box in Excel can only contain a limited amount of text. If the copied text exceeded the length limit of the text box in Excel, the pasted text would be incomplete. 3.1. Harmonization issues: Different operating systems and browser may have different restrictions on the format and length of text in the Excel table. If the copied text was not compatible with the pasted text box, the pasted text would be incomplete. 4. Paste operation problem: in Excel, copy the text by clicking the "copy" button and then paste the text by clicking the "paste" button. However, sometimes the paste button might cause problems and cause the pasted text to be incomplete. In order to avoid the problem of incomplete content when copying and paste text from an Excel table, it is recommended to check the length and format of the text box in the Excel table before copying and paste. To ensure that the length of the copied text does not exceed the length limit of the text box in Excel, and to use the paste button with the correct compatibility.
