Inserting JSON Data from Workbook1 into an Empty Table in Workbook2 with Office Scripts
This article will guide you through the process of extracting JSON data from a workbook, parsing it, and then inserting it into an empty table in a separate workbook using Office Scripts. This technique allows for efficient data manipulation and transfer within your Excel environment.
Problem Scenario:
Imagine you have two Excel workbooks. Workbook1 contains a table with JSON data in one of its columns. Workbook2 has an empty table in a different sheet, ready to receive the parsed JSON data. Your task is to use Office Scripts to automate the process of extracting, parsing, and inserting the data from Workbook1 into Workbook2.
Original Code (Illustrative Example):
function main(workbook: ExcelScript.Workbook) {
// Assuming Workbook1 is already open and accessed
let sheet1 = workbook.getWorksheet("Sheet1");
let range = sheet1.getRange("A1:A10");
let jsonData = range.getValues(); // Array of JSON strings
// Assuming Workbook2 is also already open and accessed
let sheet2 = workbook.getWorksheet("Sheet2");
let table = sheet2.getTables()[0];
// Parsing and inserting data (Implementation required)
// ...
}
Solution:
-
Reading JSON Data from Workbook1: The code starts by accessing the target sheet in Workbook1 and retrieving the range containing the JSON strings.
getValues()returns an array of strings, each representing a JSON object. -
Parsing JSON Data: To process the data, you need to parse the JSON strings into JavaScript objects. The
JSON.parse()method is used for this purpose. You will need to loop through the array of JSON strings, parse each one, and store the results in an array of JavaScript objects. -
Inserting Data into Workbook2: Once you have parsed the JSON data, you can insert it into the empty table in Workbook2. This involves accessing the target table and using methods like
addRowsorsetValuesto insert the parsed data.
Code Implementation:
function main(workbook: ExcelScript.Workbook) {
// Assuming Workbook1 is already open and accessed
let sheet1 = workbook.getWorksheet("Sheet1");
let range = sheet1.getRange("A1:A10");
let jsonData = range.getValues(); // Array of JSON strings
// Parse JSON data
let parsedData: any[] = [];
for (let i = 0; i < jsonData.length; i++) {
parsedData.push(JSON.parse(jsonData[i]));
}
// Assuming Workbook2 is also already open and accessed
let sheet2 = workbook.getWorksheet("Sheet2");
let table = sheet2.getTables()[0];
// Insert data into Workbook2
table.addRows(parsedData.length);
table.setValues(parsedData);
}
Explanation:
- The code snippet above shows a simple example of how to handle the data.
- You might need to adjust the code based on the structure of your JSON data and the format of your table in Workbook2.
- Consider using the
mapmethod to parse the JSON data, for a more concise solution.
Practical Examples:
- Data Migration: You can use this approach to migrate data from one Excel workbook to another, ensuring consistent formatting and data types.
- API Integration: If you have an external API that provides data in JSON format, you can use Office Scripts to retrieve this data and populate your Excel worksheets.
Additional Considerations:
- Error Handling: Implement error handling to gracefully handle cases where the JSON data is invalid or the table in Workbook2 is not accessible.
- Data Validation: Validate the parsed data before inserting it into the table. This can help prevent issues with data types or formatting inconsistencies.
