List sheets

$ xlsxsql list test.xlsx
Sheet1
Sheet2

Basic usage

The basic usage of xlsxsql is to run a SQL query against an Excel file. The query command is used followed by the SQL query in quotes. The SQL query should include the name of the Excel file. If no sheet is specified, the first sheet will be targeted.

xlsxsql query "SELECT * FROM test.xlsx"

For example, if test.xlsx contains the following data in its first sheet:

NameAge
Alice20
Bob25
Carol30

The output will be:

Name,Age
Alice,20
Bob,25
Carol,30

xlsxsql is an extended version of trdsql, so you can execute SQL on files such as CSV and JSON.

xlsxsql query "SELECT * FROM test.csv"

In other words, you can also do CSV and JOIN.

xlsxsql query -H -o md \
"SELECT a.id,a.name,b.price 
  FROM testdata/test3.xlsx::.C1 AS a
  LEFT JOIN test.csv AS b 
    ON a.id=b.id"

Specify sheet

The sheet can be specified by using a double colon "::" after the file name (the first sheet is selected by default if not specified).

xlsxsql query "SELECT * FROM test.xlsx::Sheet2"

Specify cell

Cell can be specified by using a dot "." after the sheet.

xlsxsql query "SELECT * FROM test3.xlsx::Sheet1.C1"

Optional if the sheet is the first sheet.

xlsxsql query "SELECT * FROM test3.xlsx::.C1"

[!NOTE] If cell is specified, the table up to the blank column is considered to be the table. ā€‹ This allows multiple tables to be specified on one sheet, and JOIN is also possible.

xlsxsql query -H -o md \
"SELECT a.id,a.name,b.price 
  FROM testdata/test3.xlsx::.C1 AS a
  LEFT JOIN testdata/test3.xlsx::.F4 AS b 
    ON a.id=b.id"

Shorthand designation

The table command is a shorthand that allows you to quickly display the contents of a specified sheet in a table format. The syntax is xlsxsql table <filename>::<sheetname>.<cellname>. If no sheet name is specified, the first sheet of the Excel file will be targeted.

Here is an example:

xlsxsql table test.xlsx::Sheet2.C1

It can be omitted for the first sheet.

xlsxsql table test.xlsx::.C1

Skip Options

The --skip or -s option skips the specified number of lines. For example, you would use it like this:

xlsxsql query --skip 1 "SELECT * FROM test.xlsx::Sheet2"

Skip is useful when specifying sheets, allowing you to skip unnecessary rows. (There seems to be no advantage to using skip when specifying Cell.)

Output format

xlsxsql query --out JSONL "SELECT * FROM test.xlsx::Sheet2"

You can choose from CSV, LTSV, JSON, JSONL, TBLN, RAW, MD, VF, YAML, (XLSX).

Output to xlsx file

You can output the result to an xlsx file by specifying a file name with the .xlsx extension as the --out-file option. For example:

xlsxsql query --out-file test2.xlsx "SELECT * FROM test.xlsx::Sheet2"

[!NOTE] You can also output to the same xlsx file as the input file. Please be careful as the contents will be overwritten.

[!NOTE] Even if you specify XLSX with --out, you must specify a file name with the extension .xlsx.

This command will execute the SQL query on the Sheet1 of test.xlsx and output the result to result.xlsx. If the file does not exist, it will be created. If the file already exists, the results will be updated.

You can specify the sheet and cell to output, if you want to output to an xlsx file. For example:

xlsxsql query --out-file test2.xlsx --out-sheet Sheet2 --out-cell C1 "SELECT * FROM test.xlsx::Sheet2"

You can clear the sheet before outputting to an xlsx file by specifying the --clear-sheet option. For example:

xlsxsql query --out-file test2.xlsx --clear-sheet "SELECT * FROM test.xlsx::Sheet2"

Multiple queries

It is also possible to output after executing an update query. A SELECT query is required for output.

xlsxsql query --header --out-header --out-file test.xlsx --out-sheet Sheet2 \
"UPDATE test.xlsx SET Age=Age+1 WHERE Name='Alice';
 SELECT * FROM test.xlsx"
