Convert Excel to JSON

Excel files are used to store textual data in tabled format with columns typically named from A to Z and rows named from 1 to 9999 or higher number.

JSON is also used to store structured data but the structure of the stored data could be more complex than a basic table. Thus, converting from CSV to JSON is relatively straightforward since you will be converting data to a format which can store more complex structures.

For conversion we can assume that a JSON file will represent Excel data as an array, where each entry in an array will be a line from the Excel table. We will also assume that first line of Excel table contains field names and other lines contain data entries for these fields. Thus each entry in JSON line array will contain mapped field names to values of the specific Excel line.

Let’s proceed with an example of a Microsoft Excel file.


Now place the following formula in the column D starting from the second row: =CONCAT("{""",A1, """:""", A2, """,""", B1, """:""", B2, """,""", C1, """:""", C2, """},")

You should get {"Name":"John", "Age":"30", "Gender":"Male"}, line as a result of this formula. Copy this formula to all the other rows in column D (to quickly copy it, select the D2 cell and click on a small rectangular section at the right bottom conrner of the cell border). Once you copy you will get following lines in column D. {"Name":"John","Age":"30","Gender":"Male"}, {"Name":"Melissa","Age":"25","Gender":"Female"}, {"Name":"Alan","Age":"42","Gender":"Male"}, {"Name":"Chelsey","Age":"40","Gender":"Female"},

To make it fully compliant JSON file add { at the beginning and } at the end of the file and remove the comma at the last line. { {"Name":"John","Age":"30","Gender":"Male"}, {"Name":"Melissa","Age":"25","Gender":"Female"}, {"Name":"Alan","Age":"42","Gender":"Male"}, {"Name":"Chelsey","Age":"40","Gender":"Female"}, }

To make JSON look nicer you can put it through any online JSON beautifier and get JSON like the one below:
